When your computer freezes up completely, don’t be trigger-happy with the force quit option and click End Task.

First, give your computer a few minutes to recover by itself. Sometimes the freeze will resolve itself.

However, if it is taking so much longer than usual or occurs more than a few times, you might have to develop another solution. Listed below are some of the most common reasons your computer keeps freezing.

An overheated or faulty external device

Excess heating of the Central Processing Unit or your computer’s external hardware might be causing the freeze. If the temperature gets too high, it can damage the integrated circuit of your system processor and permanently damage it.

Also, if the internal fans sound louder than usual and your computer feels hot to the touch, this means it is starting to overheat.


Make sure your device has proper ventilation. Finally, contact the manufacturer if you think the device is defective if it is still under warranty.

Not enough processing power or memory space

Heavy programs, like 3D rendering software and video editing applications, need ample storage to function properly.

Without heavy CPU power, your computer won’t be able to handle running these programs, especially simultaneously. Try cleaning up your storage space or limiting several opening programs at once. You may need to force-quit some apps and restart your computer to make this work.

Corrupted drive

Drivers are for making sure the hardware device and operating system work together properly. They act as a sort of bridge between the two. If your drive is corrupted, outdated, or damaged, both your hardware and software will most likely be rendered useless.

Software errors or computer viruses

Missing, corrupted, or outdated system files

System files are those that Windows or any operating system depends on to run at optimal capacity. When your system files are missing, corrupted, or outdated, your operating system will be continually interrupted from performing well. As a result, this may be causing your computer’s freezing problem or even displaying the infamous blue screen of death. Therefore, always make sure your system files are complete and updated.

Is force quitting or force shut down bad for freezing computers?

Force quitting your PC may be needed if the programs are running too slow or if everything freezes for Windows 10. Press Ctrl+Alt+Delete and open Task Manager from the list. You can then choose which programs you want to quit or to shut down the computer. You can also opt to go to the Task Manager directly; do this by pressing Ctrl+Shift+Esc and choosing which program to end.

This process is called rebooting. The risk of doing this and forcing quitting is that you may lose files and corrupt data on your system. Only do this when necessary.
