Help! My computer freezes on Windows 10


I have been using my Windows 10 desktop PC for about 3 years. Since about 2 weeks ago, my computer has been lagging and even crashing when browsing the web, running programs, and playing games. I would like to know what happened and how to fix the computer freezes randomly". 


No matter desktop users or laptop users, computer freezes always affect our experience. What causes your computer freezes on a regular basis? There are many reasons:

There are multiple programs running in the background
There is not enough space on C drive
CPU is overheating
 PC is attacked by malware or viruses
Corrupted system file
Drivers are outdated

Next, I will show you how to fix the computer freezes effectively.

What to do if computer freezes on Windows 10 and 11?

Here, we provide 7 measures to deeply repair computer freezes, including from a hardware and software perspective, you can try them according to your needs.

▶ Option 1. Add RAM or cleanup background programs

If the PC does not have enough memory, then running multiple programs in the background at the same time can cause the computer freeze due to lack of system resources. In this case, you may need to add RAM.  This is because the more memory you have, the smoother it will be to run multiple programs at the same time.

In addition, you can also clean up background programs to free up resources, which will ensure that your computer does not freeze due to multiple programs running at the same time. Open Task Manager, right-click the programs which are running, and click End task.

End Task

▶ Method 2. Scan for viruses or malware and delete them

Viruses or malware can also cause computer freezes. To keep your computer healthy, you need to scan for viruses or malware regularly. Please turn to Windows Defender or some reliable third-party antivirus software.

▶ Option 3. Clean the dust to lower the temperature

The fan in the case is used to dissipate heat, but due to static electricity, it will attract a lot of dust. If it is not cleaned for a long time, the air outlet will be clogged with dust, which will lead to the computer freeze when the CPU temperature is too high. Users need to clean the dust to improve the cooling efficiency of the computer.

Note: For more information about clean the dust, please refer to PC hardware cleaning tools.

▶ Option 4. Upgrade the device drivers

Outdated drivers and may cause computer freezes, because drivers are responsible for the communication between Windows and hardware devices. If they are outdated or incompatible with Windows, then they can be a potential factor for computer lag. Therefore, you should make sure that the drivers are always newest.

Update drives

▶ Option 5.  Check and fix corrupted system file

Computer freezing problems can be caused by missing or corrupt system files, and corrupt system files can cause many problems. The good thing is that we can run SFC (System File Checker tool) to scan and repair any corrupt system files it detects.

Type Command Prompt in the search bar, right-click and select Run as administrator, then type "sfc /scannow" in the Command Prompt window and press Enter. After the scan is complete, restart the computer to check if the computer freezes issue has been resolved.

The free space on the C drive has a crucial impact on the computer's responsiveness. Therefore, when C drive space is insufficient, extending it is an effective way to solve computer freezes.
