The new computer isn't powering up.
Hello, I just received some components for assembling a computer and my system is completely unresponsive. It briefly powers on before shutting off again. I want to note that I managed to turn it on initially and install Windows without issues, but once I powered it off and connected the old HDD and SSD from my previous machine, it stopped working. A few of my friends thought the power supply could be the problem, so I replaced it with a new one, yet the issue remained. I also purchased a different motherboard, hoping for a fix, but that didn’t help either. Then I swapped in a new CPU, which also didn’t resolve the problem. I tried using another GPU instead, but nothing changed. Finally, I updated the BIOS for both boards to check compatibility with my 5000 series CPUs (though I’m aware it might not matter since it booted once before). I’m feeling confused and a bit frustrated about what to do next.
It looks like you're dealing with multiple PC components still not working properly. Have you noticed the system cycling on and off in the same pattern? Are both PSUs receiving identical power connections? Could one of the RAM modules be faulty? When it restarts, are there signs of total power loss—no fans running and no diagnostic indicators on the motherboard?
I checked the RAM in another system, but everything seems okay. It just restarted without any fans spinning. I found a fix for this issue—it might be related to the BIOS. I re-flashed it because I wasn’t sure if it was affected, even though I’d done it before in another setup. After several attempts, it finally worked. I’m puzzled about how it booted up at all, especially since the BIOS shouldn’t support Ryzen 5000 CPUs.
