The Windows operating system và some applications installed need sufficient miễn phí space to function properly. If your system drive, generally a C drive sầu, is almost out of space, you should consider extending the system partition to create more space for your OS.

Method 4. Cheông chồng System Log in Event Viewer

Checking the system log in Event viewer is helpful to find the culprit of the "Your PC ran into a system" error in Windows 11/10/8/8.1, especially for a problematic device or driver. 

Step 1. Clichồng "Start" & enter the event viewer.

Step 2. Right-cliông xã "Event Viewer" và choose "Run as administrator".

Here you will see five or six options, depending on your Windows version, including System Restore, System Image Recovery, Commvà Prompt, Startup Settings, và Go back to lớn the previous build. Here is a brief explanation:

The registry is a database that contains the configuration data for the Windows operating system and most of the applications. That is why changes in the registry may influence the functionality of your computer or programs. Registry files may get deleted accidentally by yourself or by some program.
