Laptop not Charging Issue

MacBook Air screen at 90 degree to the keyboard.My laptop is not charging. What do I do?

If your device is not charging then it could have the following issues:

  • Power outlet not giving enough power or faulty power outlet
  • The charging cable could be damaged or faulty
  • The charging port could be damage
  • Software issue
  • Motherboard issue
  • The battery could be damaged

The very first thing you need to do when your laptop is not charging is to check your power outlet to see if it’s faulty by plugging other devices in it and seeing if it works. If the power outlet is good then you should check if there are issues with your laptop’s charging cable. Does it look damaged? Is the laptop’s charging cable have a green light indicator that it’s working properly? If not then there could be issues with your laptop’s charging cable. If there’s nothing wrong with your laptop’s charging cable and adaptor then we can move on to issues with your laptop.

After verifying that your laptop’s charging problem is not caused externally, we need to check for internal factors that could cause this. Before taking your computer apart, make sure that your computer’s battery drivers are updated.

After checking your laptop’s battery driver, check whether your charging port is working or not by using another charger and an amp monitor system. If the laptop is charging after using another charger, then there were issues with the charger and if it isn’t charging your laptop and on the amp, the monitor shows to take no amp at all then it is the issue with the battery or motherboard.

On windows to check the battery life of your laptop, just press the Windows key with X on your laptop’s keyboard. Then you can select windows power shell and select yes to the notification that says allow changes to take place. Then a new window will appear on your laptop. Make sure to type or paste this code into that window
powercfg /batteryreport /output “C:\battery-report.html”
and then press enter.
This will show you where your battery health report is saved.
Go to that folder and check your battery’s report, capacity and estimate.

On apple laptops or mac OS laptops just go to the apple icon on the top left-hand corner of the screen.
Select About this Mac.
Click on system report at the bottom of the new window pop up.
Go to power on the left-hand column of the new pop up window.
Check your battery cycle and health.
If your battery cycle is less than 500-600 then it is good, otherwise, you might need to get your battery replaced.

To check whether your laptop has motherboard issues, take it to a certified laptop repair shop near you and let the professionals handle that for you.

Graphics Card Issues

Macbook Pro on a white background with lid open at 90 degree and black screen with no display.The graphics processing unit(GPU) is one of the most essential chips and hardware components in the computer system because it helps create the visual that we see and interact with the computer with as users through manipulating and altering the memory. The most common symptoms of a GPU failure include weird lines and resolutions on the screen, intermittent restarts and shutdowns, computer lags and freezes when playing games and computer not turning on at all in the worst case, etc. There are many people who have a GPU failure because of overheating and irregular power fluctuations. We have seen many people come to our store saying they were just playing games or editing a video and then their computer shut down and they can’t open it again. Because GPU takes control of the heavy graphics processing in the computer, whenever graphics-heavy work is given to the computer then the GPU processes more and hence overheats sometimes causing the cooling paste on the graphics card to dry up and due to this the GPU experience failures. We understand how awful and counterproductive it is when your computer is not working because of a GPU failure. So, PC Service Dallas offers you with Laptop GPU replacement services where we take out the faulty GPU from the motherboard and replace it with the new GPU.

We understand that the computer is an essential part of your daily school and business/work. We want to keep your computer running well so that you can go back to your daily life. Our certified professionals will fix your computer on the same day in most cases.

What Is Computer Storage And Its Types

Alienware Tower opened up exposing hard disk drive, fan and wiresWhat is computer storage?

Computer storage is a hardware component of the computer that is used to store files temporarily or permanently in the computer system.

Let’s talk about computer storage. There are basically two types of computer storage:

  • Primary storage and
  • Secondary storage

Primary storage:

Primary storage is like the main memory of the computer where almost all the basic instructions for a computer to operate remains which is why it is the fastest for the computer to access. Primary storage can be divided into two types:

  • RAM
  • ROM

RAM : PCSeviceDallas technician holding a ram on focus with lots of RAM in the background

RAM stands for Random Access memory which is the part of the main memory which is also called temporary memory or cache memory because whatever is stored inside the RAM is temporary and gets easily wiped out if it is not saved and the power supply gets cut off. A higher ram means that the performance of the computer will be fast. You can upgrade the Ram in most cases but sometimes there are instances when there are no ram slots and the ram is embedded. In that case, you cannot upgrade Ram. In most of the newer apple MacBooks, the Ram is embedded.

ROM :

 ROM stands for Read-Only Memory. The contents of ROM are written by the manufacturer and we as users cannot change the contents of ROM. The data stored in ROM is permanent and cannot be deleted.

Secondary Storage:

Secondary Storage can be defined as any other storage non-volatile devices other than the primary storage. It can either be external or internal and can store data permanently unless it is deleted, overwritten or the hardware breaks down or there is severe damage to the hardware. Some of the examples of Secondary Storage are:

  • Hard drive
  • Solid State Drive
  • USB Thumb Drive
  • SD Card
  • CD
  • DVD
  • Floppy Disk etc.

The commonly used secondary storage device used in computers is hard drives.

So what is a hard drive?

A hard drive is a device that stores all the software inside the computer whether it be the OS or game or utility and it also stores all the data files created, downloaded or used by the user. There are two types of hard drives

  • Hard disk drive
  • Solid-state drive

Hard disk drive(HDD)

A hard disk drive is a 500g device that performs the task of a hard drive. How Hard disk drive works? It is a remarkable piece of engineering because it is designed in such a way that various moving parts need to work together to store information in such a compact space. The data is stored in an arranged pattern which is in a circular format called tracks. Each track is separated into different sectors. One of the parts of the hard drive has a map that stores information about which sector has information and which sector is free. (In the Windows Operating System this type of map is called File Allocation Table or FAT) After figuring out which sector of the track is free, the part of the hard drive responsible for writing data onto the hard drive moves to the exact location and stores information in that section. If you want to access the information it is the same process but in reverse. The access time of Hard disk drive (HDD) is 10 ms. Access time is measured in a millisecond. The time it takes to Read data is 50-100 Mb/s. This time is calculated by megabytes per second. It consumes the power of around 6W. It is a very powerful device but it has its drawbacks. Because it is engineered with moving parts if only one part of the HDD is not working, there may be a chance of HDD not working at all. Even small particles like dust can also affect the HDD. If it is close to full, it makes the computer slow. So it may not be the most reliable if it’s not kept with care.

Hard Disk Drives Piled up together for replacement

 So what do we do to get a more reliable, faster, less power consuming and lighter hard drive? We can upgrade our hard disk drive to a solid-state drive

Solid State Drive(SSD)

Hard disk drive(HDD) was a mechanical device that had physical parts moving to erase and retain data but Solid State Drive(SSD) is completely different than HDD because it uses flash memory. Flash memory uses memory chips (commonly NAND-style-chips). These chips contain semiconductors that use different types of arrays and flip them into different states of electric charge to store information. It is given the name Solid-state because none of the parts are moving. SSD is a little expensive in comparison but it makes up for its price point by delivering faster, reliable and easier service than HDD.

240 GB SSD connected to a wire for data recovery

The advantage SSD has in retrospect to HDD is that they have an access time of 0.1 ms and read speed of 200-500mb/s. This is because in HDD there are moving parts and SSD uses electricity to access data and read. Since electricity is faster it has faster process time. It also weighs less in comparison to HDD because it doesn’t need a heavy protective casing like HDD. It usually just weighs around 50g so it also has better portability. It consumes even less power than HDD because there are no moving parts that consume power. It is also said by scientists that it is seen to last generally longer than HDDs. And because it doesn’t have any moving parts it is less likely to malfunction in the new SSDs causing low failure rates. SSD can be connected to the logic board.

SSD can be differentiated by the different types of connections they come with. The connections are listed below:

SATAIII

This type of connection played a huge role in the transition from an HDD to SSD because it is the same connection option used by HDD. This was very helpful during the transition phase going from HDD to SSD but now since SSD is becoming more common SATAIII connection type has been losing their functionality. This connection can handle a maximum bandwidth of about 600megabytes/second.

PCIe

PCIe stands for Peripheral Component Interconnect Express Option. These connection types connect directly to the PCIe lanes of the motherboard of the computer giving it more direct flow to data. It makes the access speed and the read speed very fast. It supports SSD writing speed unto 1GB per second. It is a very expensive system and it increases the price of the computer significantly.

NVMe

NVMe stands for Non-volatile Memory Express is designed to upgrade PCIe connections so that they are more versatile, easier to upgrade and faster. This connection type is even newer than the PCIe and is even more expensive than the PCIe connection types.

How many types of Pin categories SSD have and what are they??

The pin categories can be categorized into

SATA pin and

mSATA pin

Display And Some Of Its Types

What is the display?

Windows User login screen on a dell laptop screen

A display for an electronic device is a part of the device which showcases the data and information from the device. Display of a computer can be divided into 2 types:

Cathode Ray Tube Monitors :

(CRT monitors used in Apple and what type of monitors are CRT)

CRT is actually an outdated type of monitor which were used back in the days to Make televisions and even used as computer displays. How it operates is there is a cathode ray tube which is basically an electron gun ray. It is positioned at one end of the display and a fluorescent screen on the other end. After there is a surge of power in the monitor the cathode ray shoots out high energy electrons from where it is to the fluorescent screen to produce data in the form of images. Apple also used CRT monitors back in 1980 with the classic Apple III computers, 2nd Generation, 3rd Generation, and 4th Generation computers.

Flat Panel Displays 

Flat Panel Displays are the displays that don’t use a lot of space which include

Liquid Crystal Display :

(LCD monitors used in Apple and what type of monitors are LCD)

How LCD Displays work is that there are a couple of transparent electrodes and two polarizing filters that consist of a layer of color or monochromatic pixels arranged schematically. When the lights are polarized in different amounts, making it pass through the liquid crystal layer, data can be seen.

Liquid Crystal Display (LCD) Important information: You will often see LCD Displays with LED which just means that the LCD Display is using a different type of backlight compared to the cathode ray tubes used in the past.

LCD consists of two types:

  • Active matrix LCD and
  • Passive Matrix LCD

Active matrix TFT 

Active matrix TFT provides better picture quality than Passive matrix Technology which is slower in response than active matrix TFT. Active matrix TFT is also secure and reliable. Due to the popularity of Active matrix TFT passive matrix TFT is becoming outdated.

There are different types of LCD Panels too. This is important to us because most of the apple computers use these types of panels in their display. To better understand the types of panels, here is a list of the panels:

IPS Technology

IPS technology stands for In-Plane Switching. IPS Panels are manufactured by Samsung. It is one of the higher-priced panels that offer the value for its money in the service department. It is considered the best technology for image quality, color accuracy and viewing angle as well. It is also popular because it is the panel technology that is the most durable than any other panel technology. Most of the mid and newer apple computers are equipped with IPS Technology.

VA Panel

VA stands for vertical alignment Panels can be called the mid-tier LCD Panels because its features stand in the right price module for the regular consumers but its features are also limited to its price module. It does perform better color reproduction and wider viewing angles than TN Panels but it comes short if it is compared to IPS Technology.

PLS and Super PLS

PLS stands for Plant to Line Switching. It is also said to be an improved version of IPS Panel Technology. It is 10% brighter, cheaper, less power consuming and even faster response time than IPS Technology. Because of its slim design and profile, it is more fragile. It may be a little cheaper than the IPS technology but it is still more expensive than other panels out there.

AHVA Panel

AHVA stands for Advanced Hyper Viewing Angle. AHVA Panels can be confused with the VA Panels but it is a completely different system than the VA Panel because it uses In-plane switching. It is manufactured by AUO just like how IPS is manufactured by Samsung. It is an IPS panel that has a similar performance like the PLS panels.

TN Panel Technology

TN stands for Twisted Nematics.TN Panel Technology may be considered those panels that may be on the bottom of the list or at the top of the list depending on what you use it for. TN Panel technology is the cheapest panel and offers the fastest response time than any other LCD panels. TN Panel technology is mostly used for gaming purposes. It is also one of the most popular and sought out Panel technology because of its affordability and it’s availability. They are capturing the market with their production numbers and cheap price.

Organic Light-emitting Diodes(LED monitors used in Apple and what type of monitors are LED)

LED is a type of screen display technology that uses panels of Light-emitting diodes as light sources to produce data. Nowadays almost all the electronic devices we use, use LEDs because they are less power consuming and more efficient. LED Panel displays have several LED panel which consists of light-emitting diodes. LEDs are more efficient because they can produce brilliant and greater intensity of light.

After knowing about how LED Panels operate let’s move on to information on how OLED works. OLED does not work with polarization like LCDs. OLEDs use a complex organic light-emitting diode called yep. These yeps light up each pixel under the voltage applied to it. The color that it produces depends upon the organic diode while the brightness depends upon the amount of voltage passed through the system. It can usually reach HDR brightness because unlike LCDs it does not block colors but the molecules put out the right colors.

How To Diagnose And Repair Your Computer

imac-osx-setup-configuration-service-PCSERVICEDALLASA computer problem can be caused because of two possible reasons. It is either a hardware issue or a software issue.

Before opening up the hardware we should isolate the issues that come with software failures.

So what are the issues that software have

  • Computer is slow
  • Computer keeps restarting
  • Keyboard, mouse, printer or other peripheral devices not working properly
  • Peripherals command interpreted incorrectly
  • App command not working in only one app
  • Slow Internet
  • Computer Freezes
  • Attachments won’t open
  • Pop-up ads
  • Google performing oddly
  • Virus infections

What are the software issues that are making your computer slow and how to fix it?

Gaming-computer-blue-screen-of-death-error-repair-service-DallasSometimes a slow computer can be fixed by rebooting it or by seeing if it can be opened from an external drive. But if doing that does not work then here are a couple of suggestions that you could try on your computer to get it fixed.

  • One of the reasons that your computer becomes slow is because of the programs running in the background. Some programs that you may not need maybe running in the background like TSRs and startup programs. In windows, you can stop these programs by going to task manager. In apple computers, there is a utility called activity monitor.
  • Sometimes a computer can be slow because there may be an antivirus scanner on the computer or another security utility that is performing scans in the background and you may not be aware of it. Since scanning the computer is gonna take more CPU usage to search, your computer’s overall performance is decreased. So you have to check your security software too if your computer is working slower than usual.
  • One of the ways your computer may be slow is because of temp files which are temporary files that are stored in your computer’s hard drives. In windows, you can delete this either by searching on the start-up menu or clicking run on the start-up menu “%temp%”. After clicking the file or running the command, you are directed to a temp folder that would open and you can delete all the temp files that you don’t use. If you can’t seem to delete a temp file, you have to know that those files are being used. The easier way is also to use a utility called the Disk Cleanup to delete temporary files but sometimes the disk cleanup utility may not delete all the files in the temp directory.
  • You can also figure out why your computer is running slow based on the amount of data stored in the hard drive of your computer. It is best to at least have free disk storage of about 200-500mb space in your hard drive because it helps the computer in dealing with increasing the size of the swap files which increase in size to increase with the functionality of RAM memory.
  • One of the ways that you may experience a slow computer is if the data arranged in your version of the operating system is not arranged in the OS’s arrangement file type.
  • One of the problems for slow computer due to software issues is viruses and malware. If your computer is infected with viruses and malware because of their self-replication and corrupting other files, your computer may be running slow.
  • Most of all of the software issues can be solved by either formatting the computer and upgrading OSX or uninstalling the problem applications.
  • What are the hardware issues that a computer may have?

One of the Main Software Issues are brought by viruses. Here are the common symptoms caused by viruses.

SLOW PERFORMANCE VIRUS REMOVAL

To gain a perspective as to what hardware issues may arise in a computer we need to know about all the hardware a computer needs to operate.

Hardware is categorized into two types

  • Input hardware
  • Output hardware.

Input hardwarekeyboard-keys-missing-computer-repair

It is hardware that is used to input commands or data or information into the computer.

Output hardware

Windows User login screen on a dell laptop screen

It is hardware that allows the computer to give out the result or output from the information provided from the input hardware.

Since these are all physical components of a computer, a computer may have an issue with any of these parts.

List of computer hardware components

  • Motherboard
  • Central Processing Unit (CPU)
  • Random Access Memory (RAM)
  • Power Supply
  • Video Card or Graphic Card
  • Hard Drive (HDD)
  • Solid State Drive (SSD)
  • Monitor
  • Keyboard
  • Mouse
  • Battery/ Battery Backup
  • Flash Drive

  • Webcam
  • Scanner
  • Microphone
  • Fan
  • Heat Sink
  • CMOS Battery
  • Daughterboard
  • Flex Cables
  • SATA cables
  • USB ports
  • WIFI cables or airport Cables

What are the symptoms of a motherboard failure?

Green motherboard detached from used computer has nothing connected to it.

These are the symptoms of motherboard failure:

  • The system does not display anything
  • Error code appears after turning on
  • There is beeping once or more times
  • The system cannot be opened and is locked
  • The system seems to reboot
  • In Windows, there is a blue screen appears
  • If one or more ports, expansion slots or memory module fails

The steps for troubleshooting a motherboard are as follows

POST test: Power-on Self Test is done when you push the power button to start the computer. What it does is when the power button is pressed, power is supplied to the CPU which seeks instructions from the BIOS. The BIOS then gives commands to check the presence and functionality of the hardware in the computer. If the test is successful then the boot is successful but if the boot isn’t successful then POST error codes appear on the screen. Each code is different and every code indicates a different hard drive problem. To isolate if there is a problem with the motherboard we need to check the power supply is working or not? The voltage fluctuations are regular or not, BIOS settings are correct or not, if there is overheating, if the fan is working properly or not, check if capacitors might be damaged, chic CMOS battery, check the POST error codes and what part of hardware or software it signifies that is not compliant with the computer system.

What are the symptoms of CPU Failures?

CPU with little pins forming a shape on the cpu

CPU is the main part of the computer that handles complex calculations and data manipulations at extraordinary speeds to give output from the user’s input. What CPU does is it loads the user’s desired input from the OSX of the hard drive of the computer and executes the instructions given by the user. To go on about the symptoms of a CPU failure:

  • If there is a chance of CPU failure when you push the power button of a computer, you may hear the computer operating like the fans and the disks may be running but you won’t be able to see anything on the screen and the screen stays blank. Sometimes it may be caused by some screen connectivity issues too. Sometimes when you have a bad CPU you might get a blue screen indicating error codes stating in numeric value that the CPU is dysfunctional during the boot process or suddenly when you’re working on your computer.
  • BIOS also can detect the problem of CPU and BIOS tells us that the CPU is not working or in a bad condition by beeping five or seven times. BIOS checks out all hardware so the number of beeps indicates the problems of different devices.
  • Sometimes if there is a problem with the fan like the fan is not working or is damaged then the system will overheat which will end up heating the CPU. If the problem is temporary then the CPU may not be damaged but if the overheating problem continues, then the CPU will be damaged hence there is a change in the functionality of the computer which is a symptom of bad CPU.
  • If you check the computer’s motherboard and see burn marks on the circuit board near the CPU or a large scorching marks on the CPU then there is damage on the CPU due to overheating.
  • To check CPU there are certain programs like Core Temp for PC and Temperature monitor and Activity Monitor for Mac. These utilities are helpful to see the temperature of the CPU, what kinds of work the CPU is doing. By comparing the stats to what a regular CPU’s stat is you can see if there is a problem with your CPU.
  • The most ideal way to deal with a bad or scorched CPU is to change the CPU or the Motherboard. You can also help increase CPU processing by keeping the system clean, using a good CPU cooler, installing supplemental case fans, upgrading your case and positioning the system properly.

What are the symptoms of RAM failures?

PCSeviceDallas technician holding a ram on focus with lots of RAM in the background

RAM( Random Access Memory is a volatile primary memory of the computer. The more RAM you have on your computer the faster the computer is because you have more space for processing. The symptoms of a bad RAM card includes:

  • Your computer is frequently freezing, rebooting, and bringing up Blue screen of Death which is a blue screen that appears with numeric error codes that signifies that there is something wrong with your computer system.
  • Another sign of bad RAM is if your files are corrupted.
  • Another sign of a bad RAM is that the PC slows down after you use it for a while but it maintains the usual speed immediately after a boot.
  • In Mac when you boot and there are three beeps noise on startup, it means there is bad RAM.
  • If there is a problem with the computer even after you reinstalled macOS or operating system.

How to diagnose this RAM problem and how to know which RAM stick is the one with the issues?

PCSeviceDallas technician holding a ram on focus with lots of RAM in the background

In windows, there is already a built-in memory diagnostic tools which you can run from the start menu or run windows memory diagnostics. A dialog box will appear informing you to restart the computer and check for problems or check for problems the next time you turn on the computer. If you click the restart now option, your computer will begin to restart and the turning on the computer will go into a memory diagnostic program and will check to see the problems. Just wait for a few minutes and you’ll get back into your windows. After that search for event viewer. In the left-hand section of the dialog box that appears go and expand the windows logs and then you have to click the system and then right-click on the system and select filter current log. Then a new screen on a dialog box will appear then just scroll down on the event sources and you’ll find the memory diagnostic results and check on it. Then select ok on the box and you’ll be directed back to the previous event viewer box. Check the top middle section of the listings and you’ll see two messages at the top of the panel with an I sign. You have to double click on the information to find out the diagnostic result from the memory diagnostic. If there is a problem with the RAM then it will show up in the diagnostic.

To check anything about RAM on an Apple computer you can click the apple logo holding option key on your keyboard and go to system information and memory and find out the information about your RAM. You can also find out problems in your Ram by pressing D or option plus D as soon as you turn the computer on. By doing this you will go into Apple Diagnostics or AHT mode from which you can know what is wrong with your computer. Another way to test your RAM in Mac is by using MEMTEST86. You download the MEMTEST86 file and Etcher. Install the Etcher dmg to your applications folder. Launch Etcher. Click the select image and choose the downloaded MEMTEST86 file and then select a drive and choose the USB you inserted which is not occupied. After that select the option Flash. The next process is to shut down the Mac and insert the USB in. After that power on the Mac and make sure that you are holding the option button. Select the USB to boot. Wait for MemTest86 to initialize and if it doesn’t select Config and then Start test. It takes around 40-45 minutes for this process. In the end, you’ll get a summary of the report of your memory.

What are the symptoms of power supply failure?

Alienware Tower opened up exposing hard disk drive, fan and wires

It is very difficult to diagnose a computer system with a bad/faulty power supply. Some of the symptoms of this are:

  • There are spontaneous reboots or irregular lockups when you are operating on the computer.
  • If the hard drive and fan would not work it is because of lack of power.
  • Since the fan would not work the system becomes overheated and the CPU’s gonna make the computer slower.
  • Getting electric shocks when you touch the CPU case or the laptop case.
  • Even when you press the power button there is no reaction from the system
  • There is visible smoke coming out from the computer system
  • You can hear popping sounds coming from the PC as it is turned on.

What can we do to find out if the power supply is bad or not?

AMD-Turion-64-processor-PCServiceDallas

We can measure output voltages by using digital multimeters and know if the power is being supplied to the system in the right amount. This process o checking the system should only be done when the system is on the load. After checking out whether the power supply is good or not, you can swap the power supply if it’s faulty but always be careful because even when the power supply is unplugged, the capacitors are still charged with a line voltage charge for a considerable period.

What are the symptoms of video card or graphic card failures?

Blue Screen Error

The most common symptoms of a graphic card or video card issues are:

  • Computer crashes can range from a lockup(meaning the PC freezing but not showing blue screen) to showing a blue screen, randomly restarting computer and computer shutting down inexpediently while running an application.
  • Because the graphics card is responsible for what is and how it is shown on the display monitor, if there is something wrong with the graphics card then the displays shown will also have problems like the screen will show threads in the display, little white dots will appear on the display, etc.
  • If your fan makes loud noises when you boot your computer or use application software that makes use of graphic cards, your graphic card may be a problem.
  • Randomly when using your computer you are notified of warning such as your video drivers have crashed and your pc restarts. If it frequently happens like this then you have a graphics card problem
  • Sometimes what can happen is if your graphic card is completely toasted then it won’t show anything, you’ll hear the fan and the hard drives but you can’t see anything on the display except a black screen.

What can be done to fix these problems?

  • We can change the drivers first because sometimes what happens is that if you have an old graphics card but you recently updated your driver then the computer will crash since your old graphic card cannot follow the sets of instructions provided by the drivers. You can install an old driver or the driver for your type of graphic card depending and it may work fine.
  • There is a cooling paste that is used on the graphic cards which help in the cooling process. Sometimes what happens is that the cooling paste becomes dry due to overheating and since the graphic card also overheats due to the cooling paste drying up. That causes problems.  Sometimes it may also be because of dust being collected in the motherboard that causes overheating or one of the fans not working.
  • Always check if flexes and cables are connected properly and that the graphic card is kept in their right slots.
  • Glitches and screen display not showing is also cases of display connectivity issues so try an external display monitor before opening your computer. Don’t jump to conclusions.
  • You can have an ultrasonic cleaning done on the graphics card.
  • The final plan is if all this doesn’t work is to replace the graphic card as a whole and get a new one that is compatible with your computer.

What are the symptoms of hard drive failures?

harddisk_datarecovery_pcservicedallas

A hard drive is a mechanically engineered device with lots of moving parts for reading, accessing, writing and storing information. So if anyone of these moving parts is damaged then the hard drive will begin to fail. Physical damage to the hard-driving such as dropping it, or spontaneous electrical surges and power outages or water damage or fire damage or it’s long usage and its age can be the reasons that your hard drives can fail. Some of the common symptoms for hard drive failure are as follows:

The first sign of a hard drive failure is if your computer frequently freezes or crashes or has reduced speed and performance. If you get freezes or crashes only once in a while in a long time, it may be something wrong with your OS, the longer you keep the computer turned off, your OS will start to act up or if you have an application that’s running without your knowledge in the background for a while, that program is taking lots of space for processing in your RAM and CPU which in turn is making your computer slower. These issues can be fixed by a simple reboot or reset. The significant sign that your hard drive is failing is if these freezes and crashes happen frequently.

If your computer is showing BSOD too often or pulling warning notifications like hard drive not found or no bootable drive found then it is another sign of hard drive failure. It may work sometime and may not work other times, but it’s just that your hard drive is still trying it’s best to work but due to either the bad cable or bad parts it doesn’t work and that is the sign of hard drive failure.

Another most prominent sign of a hard drive failure is if your hard drive takes a long time to access data. This may also be a case where you have bad connection cable but if your hard drive is old and these problems arise that is most probably the sign of a hard drive failure.

The most common parts of a hard drive to fail and is the most noticeable is the read/write heads of the hard drive which can make reading and write to and from the sectors of the platters of your hard drive difficult resulting in files and folders beginning to disappear, file names being changed, more corrupted files, reappearing and disappearing of files. This happens because the hard drive is struggling to work and can’t read the data inside the hard drive properly.

If you hear your hard drive being more noisier and your computer heating up more then it is a sign of hard drive failure. Hard drives nowadays have a technology called S.M.A.R.T. (Smart Monitoring Analysis and Reporting Technology). This technology monitors the drive’s health and looks out for the hard drive’s potential failures and sends you warnings of the drive’s irregular or intermittent failures. SMART warnings depend on the computer’s capability and also the manufacturers because the system varies from manufacturer to manufacturer.

Hard drive sounds are one or two click and some random sounds here and there but when you can hear a clicking, beeping or screeching you can know that your hard drive is failing. The first click from the hard drive comes because it’s in it’s resting position and when it’s read/write heads move from it’s resting position to the platters, they make the noise. From the platter, they find the firmware and make contact and then they can read the data. But if there is something wrong with the heads then the contact would not be made and the heads will move to it’s resting position and try again. The hard drive repeats this procedure again and again until it finally makes contact with the firmware zone which is responsible for the more clicking sounds. The beeping is occurred when the spindle motor that spins the platter thousands of rpm fails or seized when the lubrication in the motor drys off and when the heads crash into the platter and stop the platter from moving it produces the beeping noise and when the heads stop the platter, the platter starts to vibrate excessively producing the screeching sounds because the read/write heads are dragged in the surface of the platter further damaging the hard drive.

The best solution for these types of situations is to replace the hard drive and send the hard drive to data recovery facilities.

What are the symptoms of SSD failures?data-migration-from-hdd-to-ssd

It is difficult to find out if the SSD is failing because unlike Hard drives SSD doesn’t make any sounds. One way to know is to install apps to monitor the flaws of the SSD to check if it is running smoothly or not. Crystal Disk Mark is used in Windows whereas MacOS users use Smart Reporter Lite to check SSD functionality.

Some of the symptoms of SSD failures include:

  • Having bad blocks on SSD which is like having Bad sectors on HDD.
  • Bad blocks refer to those blocks of the SSD that take a long time to access, read or write and end up in failure to do so. Symptoms of bad blocks are as follows:
  • A file cannot be written or read to the SSD
  • The computer shows a message saying PC/file systems need to be repaired
  • Applications freezing up and crashing
  • When you move files from one location to another, there are error messages displayed.
  • When accessing files, the computer runs very slow.
  • Frequently crashing during boots
  • You can only read and not write to disks.

How to extend the life of your SSD?

  • Make sure your cooling in your PC works and is good and keep the computer away from extreme temperatures
  • Make sure there isn’t any intermittent power supply or electric fluctuations or outages.
  • Free up some extra space on SSD and avoid using bad blocks.

What are the symptoms of display failures?

  • Your monitor may be flashing or stuttering or flickering. Maybe caused by loose cable, incorrect refresh rate setting or power deficiency to the display.
  • Your monitor may show vertical lines
  • You have dead or stuck pixels on the screen with different colors. It means there is a single dot on the LCD screen which isn’t illuminating and is one color and doesn’t match the computer’s screen.
  • If you have cracks, spots, and blotches on the display that came as a result of physical damage to the display.
  • If you see a buzzing noise or whine noise(noise means the display does not look high definition) from the monitor then it is the issue of the backlight. It can be caused because of power regulation to one or more bulbs in the backlight.
  • If you see incorrect resolutions on your display on the computer it may be an issue of a graphics card.

What is a heat sink? What are the symptoms of a failing heat sink or fan?

burnt_connection_flex_repair_motherboard_repair_PCServiceDallas

A heat sink is a conduction based hardware component of the computer that takes heat away from the computer’s CPU. Heat sinks are installed near the fans so that they can cool the heat sink and some fans also draw cool air from outside the computer and blow it through the computer which expels hot air out of the rear end of the computer.

  • If there is a loud noise coming from the fan due to overheating inside, that may be a sign of a heat sink failure or dust or other debris inside the heatsink which is consuming the cooling space of the heatsink intern reducing the heat sink’s cooling capacity. The loud noise fan produces is because the fan is working more harder than it normally does to compensate the heat sink’s reduced functionality.
  • One of the major signs of heat sink failure is if the heat sinks have high temperatures.
  • If your computer restarts again and again, then it is the way of the computer to protect it’s CPU because if the heat sink starts failing then the temperature will rise and there is a point that it reaches the critical temperature level that the system will have to follow protocol to protect the heat from damaging the CPU by restarting or shutting the computer down.
