PC shuts down unexpectedly even when BIOS is active.
PC shuts down unexpectedly even when BIOS is active.
My machine shut down unexpectedly right after I finished work, though the fans kept running and the lights stayed on. After restarting, I checked the event viewer and saw a serious kernel error 41—more frequent than expected. I tried rebooting again, but it stopped within about an hour. It’s strange that the fans continue spinning even without a display. Here’s a sample video: https://youtu.be/h3Pf8HbboM8 I’ve gone through almost every possible fix—reset CMOS, re-seat RAM, verified all connections, even rebuilt the whole setup. I also swapped out the power supply, but nothing helped. This seems to point toward a CPU or motherboard problem. Here are the specs: Ryzen 5 2600X, ASUS RX 580 GPU, Corsair 3000MHz, 16GB RAM, MSI B450, Tomahawk MAX EVGA 600W2, 200W PSU.
I'm considering either a memory card or graphics card problem.
I'm considering using the CPU. Quickly test in BIOS to lower its voltage to around 1.2. Be cautious not to input an incorrect value while doing it fast. You might need to retry if it powers off prematurely. Check if this approach works.
I've never had any issues with either unfortunately, however the GPU does always provide an image when my pc does boot, and the fans also still spin... as for my CPU, I have no way to test that Think its worth getting a new MB or should I wait for a reply with a possible solution?
If the problem were a CPU issue, it's unlikely the system would power off in BIOS. It seems more likely the issue lies with your motherboard or power supply. I'd consider switching to a different power supply as it's less expensive and simpler to test.
I've already tried it on another PSU, same issue I'm facing now. Since I'm using a beta BIOS, I'll update to a non-beta version to check. If that doesn't work, I'll have to purchase a new unit.
I believe I’ve reduced the options to either GPU or MB. It seems unlikely to be CPU since the pins are intact and I’ve maintained good care of it over the past year. After further testing and updating the BIOS, a VGA light appears, suggesting no GPU was detected. Switching to a different PCI slot didn’t help. Should I upgrade to something better than the RX 580 or is it still MB?
