Hey there, Bart. I saw you're dealing with a tricky problem with your PC. It sounds like the issue might be connected to the power supply unit or the motherboard. Sometimes the system powers down unexpectedly and tries to restart, but it doesn't respond properly. You mentioned trying resets and holding the power button, yet nothing changes. The fans spin, but the computer remains unresponsive until later. You noted that after a short period of inactivity—like 5 to 30 minutes post-sleep—it starts working again, which could point to a power state issue. Your setup has mixed components: the motherboard, CPU, and RAM from one PC, while the PSU, GPU, SSD, and peripherals are from another. The motherboard looked fine when you used it with a different PSU, so it's possible the problem lies with that unit. I'm guessing the PSU might be faulty, but it's also conceivable the motherboard is the culprit. Let me know what you think!
