I have a strange problem with my computer. I will try explain the best way I can.

After shutting down the computer it can not boot up until i unplug the powercord and let it rest for well over an hour. I don't know the exact ammount of time I need to wait before it starts up again but over night it will start the next day.

If i switch the psu power switch off and on the fans will spin just a little then stop, but nothing happens and the cpu wont start. If i just press the powerswich up front nothing happens at all. If I unplug the ATX 12V connector the psu boots up and all the fans start. But the CPU wont start ofc.

When i plug it in and switch the power on the psu both the usb light and mainbord green light ligts up.

Could it be a short or a grounding problem?

I'd swap the mobo.

I'd be tempted to try another PSU before I changed the mobo if you can borrow one.
