Hi guys, so my PC started behaving a bit strange.
On cold boots it would refuse to post, or half post and die. On one occasion I got into Windows and the system hung.
The strange thing is this issue will rectify itself if turned off for a few minutes then trying again.
I initially thought ram could be a culprit so I ran memtest when the PSU was in a working state and it came back passed with no errors.
I then got a PSU tester which revealed that the Power Good signal was outputting only 10ms, which should be 100ms or greater from my initial research. Sure enough after waiting a couple minutes and booting again the PSU tester registered 300ms for Power Good, which would be normal.
Im now wondering if this is enough to determine a faulty PSU or if the local grid may be at fault or overloaded at peak times (PSU gasping for air on first few boots).
The other figures are within the manuals tolerance.
Thoughts guys? I'm pulling my fucking hair out.

Change the battery on the mobo.

Shouldn't have anything to do with it considering the PSU tester noticed the issue without the mobo connected

Add a capacitor to the PG line.

M8ey leave my shitposting out of this what if my electrical company is jewing me with dirty power

Status update:
5v rail is fluctuating to 4.9v and PG after being left off for a while has returned to a low value.

then you should be checking your outlets not your PSU
Or you could just buy a UPS or power conditioner.

4.9v isn't a worry at all, lines can fluctuate by +/-0.3 quite happily.

Just jam the positive leg in the back of the PWR_OK pin and the negative leg in COM next door.
I would recommend buying a pack of capacitors of various values off amazon or a local electrical store. The higher the capacity of the cap the longer it will take to pass power through it, so the later the signal will arrive, so start small. ATX spec says anywhere between 100ms and 500ms is considered normal.
