PC posts from time to time

ILoveZed · October 24, 2023

The computer turns on normally just from time to time. If it refuses to turn on it would only spin up the fans, turn on leds (excluding the drive activity light), hard drives and everything that’s not an external component. Everything else has no power including monitor, mouse, headphones and any other accessories. No post error from the internal speaker too.

Sometimes it would get stuck booting too. It turns on for a few seconds then shuts off again a couple times.

I used to be able to force it to post by shutting power off and on quickly from the power button of the PSU, but now it doesn’t work every time.

if it does turn on, sometimes an “(A7) Me FW Downgrade - Request MeSpiLock Failed” error would come up followed by “Error sending End Of Post message to ME, System HALTI”.

Also when it turns on normally sometimes everything would freeze for a few seconds and it would fix itself or I’d have to restart it.

The system is about 10 years old. I tried replacing the motherboard and updating BIOS, but that didn’t fix the issue.
