I'm not a very experience computer builder but this past summer I put together my own. Specs: GFX - Dual radeon 7870's
Processor - Intel i7 - 3770 3.4
Memory - 24GB
PSU - Corsair 750W
My most recent change has been the graphics and power. Ever since I got dual graphics, ill be playing a game with some friends and my computer will freeze and ill have to hold the power button to turn it off then back on. I tried moving it away from my desk thinking it was overheating but still, same problem. Please help.
