yeah i suspect that thats the prob, thanks for directing me there. But now i just spent about an hour searching for what could have been grounding it but to no avail. I took the mobo out and made sure there wasn't any lose screws grounding it. The comp acts pretty wierd, it turns itself on with a little bump or if i shake it (but turns off after about 3 secs). Any tips on where to look for what could be grounding it? like one of the metal on the pci cards or something? any suggestions would be great. thanks!
