8 Reasons Why Your PC Keeps Crashing
Below are some of the common reasons that are causing PC crashes. PC crashing is not a common issue and it required proper diagnosis and timely action to keep the PC and data safe.
1. Overheating

Overheating is a common cause of PC crashes. When your computer gets too hot, it automatically shuts down to prevent hardware damage. This is a protective mechanism built into your PC to prevent hardware failure. The most common cause of overheating is a buildup of dust and debris inside your PC. The solution to this is to clean your PC regularly and ensure that all fans are working correctly.
2. Hardware failure
Hardware failure is a common cause of PC crashes. Faulty RAM, hard drives, and other components can lead to crashes. If you suspect a hardware failure, you can run a diagnostic test to identify the problem. In this case, you will need to replace the faulty component. If you have recently opened your PC for cleaning or for upgrading, make sure everything is firmly placed at its location otherwise it will lead to a PC crash.

3. Power supply issues

An insufficient power supply or a faulty power supply unit (PSU) can also cause your PC to crash. If you are using less voltage PSU and it might crash the whole PC because of insufficient power. In this case, you may need to replace your PSU with a higher-rated one to ensure that your PC gets enough power.
4. Corrupted system files
Corrupted system files can cause your PC to crash. You can use the System File Checker (SFC) tool to check for and repair corrupted system files. When a system file becomes corrupted, it can cause various problems, such as the blue screen of death (BSOD), random crashes, freeze-ups, and other system errors. These issues can be frustrating and lead to data loss or damage to your hardware.

Using System File Checker (SFC) tool, which is a built-in tool in Windows, you can scan the system files and found out the corrupted files.
To run the SFC tool:
- Open the Command Prompt as an administrator.
- Type “sfc /scannow”.
This process can take some time, depending on the size of your hard drive and the number of corrupted files. Once it is done, you will see the corrupted system files but if there is nothing with the system files, it will say “Windows Resource Protection did not find any integrity violation” which is a big relief, to be honest.
5. Overclocking

Overclocking is the process of increasing the clock speed of a computer’s central processing unit (CPU) or graphics processing unit (GPU) beyond its default or rated speed. This is done to improve the performance of a computer, particularly for gaming or high-performance computing. Overclocking your CPU or graphics card can cause your PC to crash. If you have overclocked your PC, revert to the default settings to see if the crashes stop.
6. Incompatible software
Incompatible software can also cause your PC to crash. When you install incompatible software, it can cause your PC to crash or become unstable. This can happen if the software is outdated, or if it conflicts with other software installed on your computer. Incompatible software can also be caused by running software that requires more resources than your computer can provide. It is important to check the system requirements before installing any software to avoid compatibility issues.
7. Malware and viruses
Malware and viruses can infect your computer and cause it to crash. This is especially true if you frequently download files from the internet. Ensure that you have up-to-date antivirus software installed on your PC to protect it from malware and viruses.
8. Outdated drivers
Outdated drivers can also cause your PC to crash. Ensure that all your drivers are up-to-date, including your graphics card driver, which is essential for gaming. Otherwise, it will keep crashing your hardware and it might lead to loss of data.
