Please help all computer gurus, I don't know what happened to my graphics card! I was merely browsing the internet when all of a sudden all my monitors go black and my GPU fan went to 100% speed. I tried rebooting but I get no signal to my monitors even though I hear the Windows loading sound in the background. I also tried reseating the video card but still no results. I have a PowerColor 6870 that was recently bought only a month ago. I took it out and put in my old 4850 and the displays came back. I'm thinking the root of my problem is my graphics card, but I just wanted to double check with the gurus out here. Temps for the PowerColor were ~36-40 idle, and ~65-70 load.

My other thought is that it could be my PSU. Here is my build.
-Mobo: Asus M5A87 am3+ (new <2 weeks old)
-CPU: AMD Phenom II x6 1055t (new <2 weeks old)
-Ram: G Skill Rip Jaw 8gb 1600 (new <2 weeks old)
-GPU: Powercolor 6870 (~3 weeks old)
-Hard Drives: 60 OCZ vertex, 250 Seagate Barracuda, and a 1Tb Seagate.
- PSU: OCZ StealthXStream OCZ600SXS 600W ATX12V / EPS12V (from old build, ~3 years old)

So my questions are:
1) Did my GPU take a dump on me? Should I go ahead and do a RMA?
2) Is it just my PSU is not strong enough? Although everything was working fine for 3 weeks with the new parts.

Any help is greatly appreciated.
