Device suffers from repeated unexpected shutdowns.
Device suffers from repeated unexpected shutdowns.
The issue is straightforward: the machine boots right after powering on, fans begin spinning, the video card display lights up, and then it abruptly shuts down as if reset. After some time left unused, it can restart normally into Windows but then powers off unpredictably—ranging from a couple of hours to several days. I’ve swapped out two different power supplies and cords, tested various RAM sticks, but the problem persists. I’ve removed everything except the CPU and RAM (PSU still connected) and it keeps failing. I’m hesitant to modify BIOS in case it crashes during an update, which could worsen the situation. I’m at a loss and don’t have another board or CPU on hand. Please help.
Specs:
- Intel Core i7 10700 @ 2.90GHz CPU with built-in graphics
- ASUS Prime B460M-A motherboard, BIOS version 2.20.1276
- 16 GB 3200MHz DDR4 RAM
- Gigabyte OC 2060 Super
- Kingston A2000 1TB M.2 drive
- Cooler Master MWE 80plus White 750W PSU
- TP-Link AC600 Wireless Archer T2E
- Windows 10, 64-bit version 22H2
I don’t see that specific BIOS version listed on the ASUS site. BIOS numbers are typically around 1620 or 1602. Could you share the make and model of the other PSU you tested? Also, let me know if you’re using one cable or two to your RTX 2060 Super. If everything was functioning normally without it, did you remove the GPU and check for power issues?
The BIOS version was visible before it stopped working again; sorry about that. The two PSUs and the third one were all the same as the first, using daisy-chained connectors. I mentioned I've tested the machine with everything except the motherboard, CPU, RAM, and the PSU—still facing the same issue, suggesting the problem isn't with the card. I'm considering a CPU fault because I had overheating issues before, so it might be heat damage.
