Strange Power Problem!
I am posting on behalf of a friend.
He had a standard PC desktop system (I don't know specs, sorry), but the other day he went to switch his computer on and it would not start. There is seemingly no power running to the motherboard or drives at all, although when he pushes the power lead in the back the lights on the motherboard flash and the red light under the mouse also comes on!
I suggested he replace the PSU, which he has done, but has exactly the same problem!
If there is no power to boot the system, how can the keyboard and mouse be drawing anything?
What's next? Change the Motherboard, or (next?) the CPU?
All advice appreciated.

So...it sounds like when you press the power cable into the PSU harder you can operate the PC normally? Is that right? Did you try replacing the cable itself?

Hi, no that is not what I was on about!
When you push the power lead into the PC it does nothing, but the keyboard lights flash and the mouse lights up on the base!

Do the fans stay on? If not maybe something is causing an overload on the psu, most will automatically shut down on overcurrent situations.

Same thing with two PSU - one brand new...

I'd still replace the main power cable, just to be sure. But it honestly sounds like a loose cable somewhere; despite the fact they've all been reseated since you've installed a new PSU... I'm drawing a blank right now...
