I have a PC that works perfectly when running, but when you power it down, it refuses to power up again.
The background is as follows:
After my motherboard got fried (I suspect too muchpower being drawn, frying motherboard connectors), I replaced the modo with a Gigabyte &VM400M-RZ, and the power supply with an Antec SL350P
I friend of mine stripped and re-assembled it all for me.
Now for my problem:
It powers on ok with nothing connected, but refuses to do so otherwise
As the PC belongs to my wife (who shows severe withdrawal symptoms), I left the power on and let her use it.
I then bought her a nice, sparkling new PC, and decided to fix hers once and for all, expecting an earthing problem.
Stripped the case and rebuilt it - no change.
I then removed all peripherals (the Gigabyte has all a basic user needs) and tried again - no luck
I tried the motherboard completely out of the case, then it powered up for me. Drop it back into the case, and it stops powering up.
Where do I start looking next:
A faulty new Antec power supply ??
A new Gigabyte mobo?
A crappy old case?
How exactly should a mobo be earthed (or not).
Should the top of the holding screws be electrically connected to the case (i.e. earthed)?
What about the mobo surrounds of the screws?
