shutdown issue Consistent PC Shutdown Problem

jheafpp · October 9, 2022

When I hit the power button, the PC powers on for a second before shutting down again.

Before this there were several random moments where it shutdown for no discernable reason, and the period between the shutdowns seemed to get smaller and smaller until it doesn't stay on for more than a second.

I tried looking at Windows Event Viewer, but I didn't know what to look for and any critical errors I did find didn't seem related to the power situation.

1) cleaned out the PC of the dust

2) I replaced the PSU AND the power cable.

3) Had it assembled and reassembled by PC repair shop, twice. They said the components were working fine and suggested it was a power cable problem.

This fixed the problem for couple of days until the shutdown problem happened again.

4) Now I found out the new wrinkle in the problem, that given a whole day the problem fixes itself, but I'm not sure if it's a permanent fix.

Has anyone else faced the same problem?

edit: the problem came back, but I unplugged it and plugged it into another socket in the power strip. And the problem is solved for the moment.

A friend suggested the issue might be the fuse for my room might be faulty, but if that was the case it would affect the monitor, the lights and the ceiling fan too.

I really need an answer because my job requires that I run a program for 6+ hours, and need reliable power for my computer.

Initial problem is fixed, but I still need to know the cause because I need to know whether to replace the pc or the fuse in the room.
