Short on motherboard of new computer?
I'm putting together a new computer. I've got everything hooked up and I find that it either won't turn on or only does for a few seconds. One thing I noticed is that if I press lightly on the bottom right corner of the mobo, it will turn on and will stay on - until I stop pressing. I assume that this is flexing the mobo ever so slightly and either breaking a short or completing a circuit.
Shall I assume this is a short and return the mobo. It's a long drive. =(
The mobo is an Asus P8H67-M-LE with and i5-2400 and a 420W psu.
Hmmm, seems to work fine outside of the chasis. But nothing in the chasis seems to be touching the mobo but the brass standoffs, the screws that go into them, and the io plate.

take everything apart. i think the problem that you are facing is that you have a misplaced standoff between the motherboard and your case. that is probably why a short is possible, also check if everything is plugged in correctly
so test your motherboard and all your components outside of your case just to see that it's working, then carefully check that the brass standoffs that screw into your case underneath your motherboard line up perfectly with the holes on your motherboard

>Make sure that NONE of the motherboard is touching ANY part of the chassis EXCEPT by the brass or plastic stantions on the support holes! Reseat the motherboard and this time make absolutely sure NOTHING from the motherboard is touching ANY part of the chassis. Also, make sure there are no wires from the power supply or any other source that is a naked end (bare wire) touching the chassis or that is connected somehow to the motherboard.
On most motherboards there is a shorting jumper. This is typically a three pronged jumpered connector on the motherboard. Make sure you did not LEAVE the shorting jumper OFF of the board or that it is jumpered to the shorting position. Typically, on a three pin, 1,2,3, non shorting or default setting is pins 1,2 and shorting is pins 2,3. So make sure the jumper for this is set to 1,2 on the position of the connector if you have been playing with shorting the board (in order to reset the BIOS).

What you can also test is out of the case. Hook everything up outside the case on a non conductive material like a kitchen table made from wood.
I have gone into problems with some Thermaltake cases in the past.
Check all your options one by one before waisting time and travel.
Good luck !
