The PC shut down several times before completely stopping POSTing.
The PC shut down several times before completely stopping POSTing.
It's a 2019 built computer, so I started by opening a few folders and it shut down twice before stopping again. I played for a while, then came back this evening. When I turned it on once more, it booted to the desktop but the keyboard and mouse didn't respond at all, so I had to restart it.
Later, it failed to POST, and the red light on my motherboard stayed lit.
I've tried several fixes:
- Updated the BIOS
- Performed a CMOS reset by removing the battery
- Realigned the CPU and re-flashed the BIOS
- Removed all components except the 24-pin and 8-pin, then flashed the BIOS again
- Attempted booting with a single RAM stick
Nothing worked; the CPU light stayed on constantly.
Details:
MBD: MSI X570 A Pro
CPU: Ryzen 5 3600X
GPU: RTX 3060
PSU: Antec NE650M GB
I consulted another PSU and found the same issues; the CPU isn't heating up properly. Testing with another RAM stick (all slots) confirmed no problems there, and checking on a different motherboard showed normal operation. It’s clear the issue lies with the motherboard itself. I’m not planning to upgrade it soon, so I’m curious if a B-Series board would work well for this build. Any advice would be greatly appreciated.
