Device shuts down unexpectedly.
Device shuts down unexpectedly.
Not long ago I assembled a PC with these specifications: CPU i9-12900F, cooler be quiet, graphics Palit RTX 4090, motherboard GIGABYTE Z690 AORUS ELITE, RAM Patriot Signature Line (DDR5 4800MHz 2x16GB), power supply DeepCool PX1000G, case ZALMAN Z10 with stock fans, two 120mm and three 140mm fans. It generally functions well, though occasionally it powers down abruptly for a brief cooling boost—usually under light load and sporadically. No overclocking or undervolting was done; everything stayed at default settings. Temperatures were around 30°C for the CPU and about 40°C for the GPU when I checked stats just before another shutdown. Updating drivers and firmware didn’t resolve the issue. I discovered the BIOS offered a "Power Load" setting, which matched my problem. It didn’t help either. The issue isn’t linked to the operating system, as the PC would restart normally after a reboot. Windows logs show it rebooted cleanly without a full shutdown. This could stem from the system failing to respond, crashing, or losing power unexpectedly.

I would begin by inspecting all the power cables for any issues. It might help to check the wall power cable as well. Then I would test using a different power supply. Having more functional components available makes troubleshooting easier.
It looks like the power supply is functioning properly after the performance boost. It doesn’t appear to be overheating or struggling under load. You might want to run diagnostics like DISM, SFC, and DDU for thorough checks.
I organized the journal, but only the major issues were found, consistently at the moment of shutdown.
It occurs in BIOS/UEFI too, so adjusting Windows settings likely won’t work. As I said before:
I completely rebuilt it during troubleshooting and relocated the M.2 SSD to another slot "just in case." I'll attempt it again tomorrow. I'm not sure it will make a difference, but it won't hurt either, so I'll give it a shot. The motherboard and CPU are relatively new, like other components, though I can't confirm their condition. I don't know how to test them separately without getting replacements, which isn't possible. Not really, I don't have a dependable USB drive. I should consider buying one first. Also, the PC appears stable once more. It shut down three times within about 20 minutes after startup, then it stabilized and functioned properly. That's an unusual behavior...
Today I encountered an evolved issue and received a big clue. Before powering off, the system worked after restarting, but now it didn’t boot at all on the first try—only five short beeps appeared. The second attempt was fine. After a few minutes the cycle restarted: turning off, then a beep, followed by a correct Windows boot. According to Google, this suggests a CPU problem, so I cleaned the CPU contacts gently with alcohol. Since the problem occurs unpredictably, it’s unclear if that helped, but no random reboots have happened yet. I’d feel foolish if it was a hardware issue, so I sent both the CPU and motherboard to the shop for replacement or repair, hoping to return in a few weeks with the note “I don’t know, looks okay.” At least it didn’t cost anything except time.
