PC Keeps dying at random intervals

[BocchiTheRock]

The past 5 days, my PC has been dying randomly throughout the day—whether during heavy gaming, idling, or just browsing the web. Initially, I thought it was a power issue, but the other devices connected to the socket were working just fine. I used Event Viewer and attempted to fix the issues there, but to no avail. Now, I've tried to reinstall Windows 11, and I'm stuck in a loop where it restarts right before the initial setup is done. Is there something else I should check before considering shopping for a new one?

Do you have another motherboard, CPU, and memory that will support your current systems socket to test to see if its a hardware issue? If so try that, if not ask a friend who has some of the same hardware if possible to allow you to test to figure out which parts are bad. Its better than having to waste money on a new PC.

Not really, the system is a SSF, my old PC is a 2002 Intel, I don't think they are in any way compatible, and if it's the PSU as I suspect, it's more expensive in this format than another decent PC.

Its super cheap so still better than buying a new system even if you need to replace the power supply.

I will try this, thank your for your help.
