Okay so this recently started happening on my Sapphire HD 7970 3GB GDDR5 .... It only happends when I run a graphically intensive game. I can't even get through the first test on 3DMark... i'm starting to think it's my power supply because I recently got some new parts for my computer.. please help... Here's my specs.. I'm hoping my GFX card isnt shitting out on me..
Motherboard: AsRock Z77 Professional
CPU: Intel core i5 3570K 4.0GHZ
RAM: 16GB DDR3 Corsair Vengence
Video Card: Sapphire HD 7970 3GB GDDR5
Power supply: Thermaltake TR-600P TR2 Series ATX Power Supply - 600W
