The issue might be intermittent, so checking for power issues or temporary glitches could help.

In short, he received a used CPU from me that I’m 100% confident will function properly without problems. It worked before I upgraded to a newer model, and now the PC behaves as shown in the videos. Sometimes it runs games smoothly, other times it just plays according to what’s on screen. This is the third time he mentioned this issue. I suspect the power supply might be the problem, but heavy usage doesn’t seem to cause an immediate shutdown. He claims all cables and components are secure, and the thermal readings look normal. I’ve even shared a video where turning off the CPU power connector prevents booting, though the system still powers on normally. It’s unusual for this to happen on a PC.
It might be the power supply unit rather than the connector. The motherboard could also be a factor, though less likely. I’d consider replacing the PSU first—if it doesn’t help, return for a refund and try the motherboard instead. If you manage to find a reliable PSU, that would save you from purchasing one.
