This has been ongoing for a couple of weeks.
I switched on one day and the 'ol tower PC refused to power up. I use an anti spike plugbar and could see everything else was ok. Router, screen etc.
As it happened I had a new power lead to hand and used it for the first time to get the PC up. No probs.
Next day, PC no power up..
Put a new fuse in the old lead, even though the old fuse tested ok. PC powered up.
Next day PC no power up..
Swapped lead and PC powered up.
Next day PC no power up
I did have 3 days where the lead swap wasn't needed, but it soon came back.
I know it seems like no biggie, and I've dismantled the plugbar and pinched up the contacts inside a bit so I have to use a little more 'push' to put the mains plugs in. So that isn't the issue. It doesn't seem to be the PSU mains connector, as unplugging and re-plugging the existing lead should fix it if a different lead also fixes it. I've tried waggling the lead plug in the PSU and hitting myself on the head with a stick. No benefit from either.
So what the is going on?
Will my house burn down?
