BSOD + Freezing Error

Let me first say:

SYSTEM SPECS:

Windows 7 64 bit
8gb RAM
EVGA GTX 570 HD SC
650 WATT Power supply
AMD PHENOM II x6 1100T (6 CPU) 3.3GHz

I'm having two problems as of now. They probably relate but anyhow:

Firstly in games I usually get to the point that my card freezes (N) and the screen shuts of and I have to manually reboot the system. Sometimes instead though it'll be a bluescreen and error says:

"Problem signature:

Now what I will say is YES I did recently reboot my windows to see if it fixed the problem and it just didn't work!

Anyhow below is the Rar folder!

Welcome to sf.

Your drivers look up-to-date. Two questions...

- are your overclocking your gpu?

- are you able to monitor the gpu heat?

I'm not overclocking from what I know. I've had someone else ask me that same question. I just did a clean boot up of windows 7, and I'm not sure on how to check if I've ever overclocked my GPU before.

I do monitor heat and I don't go over 55 C or 60C so I don't think heats the issue here?

Your temp is not a problem.

Download furmark (free) for video diagnostics...

FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

Downloaded, so I run it and report back soon or?

What am I exactly looking for?

Average stuff seems to be:

GPU Load: 99% Mem Load: 11%

Temp: 80 C

AVG Fps: 18

It's an ASUS motherboard from what I know of, when I open it I can't really see what Asus it is but I can tell you it's Asus :P.
