So I've been dealing with this for quite a while, throughout multiple different OS systems (Windows 10/11/freshly reinstalled Windows 10). Still, my C drive would randomly spike up to 100, freezing the computer, and sometimes follow up with a BSOD, paging critical_process_died. I was running Windows 10 when I first encountered this problem. Hence, I freshly reinstalled Windows 10, and the problem did not occur for a while until my PC was automatically updated to Windows 11 about a month ago. Now it's happening all over again. Sometimes it happens when the PC is idle, and sometimes when I play video games. I tried most of the basic problem-solving like SFC scans, or checking the health of my SSD and such, but nothing seemed to ultimately fix the problem.
