Right off the bat, I'm not too big on hardware.

I moved my computer (Along the same wall, different outlet) to a new location and ever since then it runs for 30-45 minutes and shuts off.

I checked tempatures, CPU was around ~40C and the GPU was around ~45C, so I'm not sure if it's an overheating issue. I also checked any loose connections etc. Could it be the Power Supply? If that's not it I'm guessing it's faulty hardware some where.

Any suggestions?
