Question: PC - CPU Error or Won't Post
I have a malfunctioning computer, it's quite old and I plan to repair it again after inspecting it. It appears the main issue is with the CPU. According to some online sources, it might be due to insufficient voltage being sent from the PSU to the motherboard.
I use this particular PSU, but I recall facing similar problems in the past. When I try to shut down the PC, I have to manually press the power-off button—it doesn’t work through the usual method. If I try the normal shutdown process, the PC stays on but the fans stop working.
Last moments before the crash: it would freeze while I was browsing YouTube for about an hour, then suddenly it would freeze again after I tried to restart. I haven’t had time to investigate further, so I forced a shutdown and then restarted, but nothing changed.
What I have attempted:
- Reset CMOS
- Reset RAM settings and used only one stick
- Disassemble everything except the motherboard fan and turn it on
- Inspect the motherboard pins (I’m worried something might be loose)

If I leave it running for a couple of minutes, it shuts down and then turns back on.
Note: I’m in a difficult financial situation, so I don’t have any spare parts to test, and now I’m considering purchasing new components. I suspect the issue could be with the processor, motherboard, or PSU. But I’m unsure which one to fix first because I don’t have enough funds.
I hope someone can help me understand what to prioritize or how to proceed with repairs. Thank you for a great day.

Hy!, I've made the update. Yes, the PSU is working with its new model I purchased last year...
I just purchased a new motherboard and processor, and after installing the new components, everything is functioning properly. It looks like the issue might be with the CPU or the motherboard itself. I’m assuming the CPU is the main concern.
