Why does Win 11 reboot randomly?

Question

win 11 will randomly reboot without warning. Sometimes it will reboot 3 or 4 times in a row. Sometimes it will reboot just once a day. Sometimes it will go all day without a reboot. It does not matter if the pc is under load or idle. Temps are between 40 and 50c on cpu and gpu so its not overheating. I have done a complete reinstall of win 11 and it seemed to fix it briefly but has started again. PSU voltages are within normal range.

Thanks for sharing the files.

The minidump file indicates nvlddmkm.sys file as a cause of the BSOD which is related to the Nvidia Graphics card driver.

If you do have an Nvidia graphics card installed on your computer, try to uninstall its driver completely using this DDU free utility, then download/install the latest graphics card driver or a driver that is compatible with your computer from the manufacturer's official website:

If it did not help, install an older version of the graphics card driver. Sometimes, older versions work more smoothly rather than the latest ones.

Or, you can download GeForce Experience to keep your drivers up to date:

If you are overclocking your PC, try running everything (CPU, GPU, system memory) at their stock speeds. See if the issue is still reproducible. Turn off XMP profile or set it to Auto.

If your computer still encounters BSOD, test the RAM with the free utility MemTest86, then run a full 8 pass scan to test your RAM for physical errors:
