I'm at my wit's end with this problem. I've replaced almost every part of my PC, including the GPU, CPU, CPU fan, RAM sticks, and power supply unit (PSU), but it keeps rebooting. Sometimes, it turns off and shows a black screen before starting back up again. I've had moments where I think it's behaving properly—lasting a few minutes—only for it to turn off again. Occasionally, it won't even let me do anything for more than a minute before rebooting. I've also tried making some adjustments in the BIOS, like enabling Precision Boost Overdrive (PBO) and turning on XMP, and even reset Windows. It ran a bit longer after that, but the rebooting continues. Any advice?

I went through something similar, and it turned out that after upgrading my motherboard and GPU, my PSU couldn't handle the load. I ended up upgrading to a higher wattage PSU, and everything started working fine afterward.
Resetting your BIOS to optimized defaults might help, but if the crashes persist, try running a Memtest with a live USB or CD to check if your RAM is causing the problem.
Have you tried clearing the CMOS? It's a handy step that can help reset your BIOS settings back to factory defaults which might fix the issue.
I’m not really familiar with how to do that. Could you give me some guidance?
I actually had a 650W PSU before, and my current one is 550W. Neither has solved the issue, but thanks for the suggestion!
