  Random PC Resets and Lockups. 
 Date Written

Lately my pc has been either resetting itself or locking up all together. At first it was only occurring during games such as wow or even low end stuff like empire earth and SOASE. So, i switched out my current graphics card which was a gtx 480, for a 250 gs. and for a little bit, it worked okay. then it started having the same issue. i read more into is and thought it may be my power buttons shorting out seeing as in how i did the wiring myself and figured i needed to rewire them anyway. so i did that, and i installed the 480 again, and decided to run the 250 on physx, also, when i was rewiring, i reseated everything, including cpu and memory sticks, and i reseated all psu wires and data cables. again, worked great for a few days, then did the same thing. so today i did it all again including the reseating and i also reformatted and reset the raid, this time it started acting up almost immediately. so i feel its narrowed down between mobo and psu, and seeing as in how i replaced the motherboard less than 5 months ago and its just now starting to act up i figure its possible the psu, but, im looking for second opinions as always. any help would be appreciated.
