Power Switch Problem

I recently Built a new system and all went well...
Everything was running fine until i began getting random shutdowns
the sytem would shut down and then not restart again unless left alone for a couple of hours.

So i went through the motions and narrowed the problem down to a fault with power switch either on the mobo or the case. I have the Haf 932 case and Gigabyte ex58 ud5 mobo.

When the power switch from the case is not connected to the mobo i get no random shutdowns at all. I opened the case but all the connections are Glued in place. I thought maybe the guys from Coolermaster may have mixed up the jumpers on the case putting the positive where the negative should be and vice versa.

So i have switched the jumpers around on the motherboard and it starts and shuts down fine using the power switch but im just waiting to see if i get the random shut downs.

Am i risking damagin the mobo swapping these wires around? can you guys think of any other reason why id be getting these shut downs?

Also what are your temp like?

It does seem that the power switch may be the culprit then as you have eliminated other possibilities.

This should hopefully tell you if it is the power buttons fault or not:

Go to Control Panel\Power Options.

Under the power plan you are using, hit "change plan settings", then on the next screen choose "change advanced power settings".

Look for "power buttons and lid", change power button action to "do nothing".

Now Vista should ignore anything the main PC power button is telling it to do.
