Hello, I just ran the FurMark Torture Test for 30 minutes 1920 x 1080 with 8MSAA and ran into no problems. My maximum temp was 70 degrees Celsius (highest temp I've ever gotten) and an avg. FPS of 34. I will edit this post with how I do in different benchmarks as I do them.
Unigine Valley: Max setting ran just fine several times consecutively with a max temp of 60 degrees Celsius
FurMark: Ran 1920 x 1080 with 8xMSAA max temp of 70 degrees Celsius
OCCT: I ran OCCT just fine for 30 minutes with 7 shader complexity and a resolution of 1920 x 1080. I got a max of 52 degrees Celsius and I didn't go below 60 FPS. I almost think I missed some more intense graphic settings
Unigine Heaven: I maxed out all the setting I could find (with the exception of my 1920 x 1080 resolution) and I even turned the tessellation sliders all the way to the right (I dont even know if I should do that, but I could a big drop in performance so why not stress my GPU even more?) and the FPS was pretty horrendous, staying mostly in the 20's, and my max temp was 70 degrees Celsius. I had no problems whatsoever.
I wont do any more benchmark testing because I feel very confident that my BSOD is not a result of a faulty GPU, but I will move on to testing each of my 4gb RAM sticks just to try and see if they may be to blame. If the RAM is not faulty, I will move on to my old GTX 660 OC SLI configuration to see of I still get BSOD's. Cheers for now everyone
Edit: is it possible my weak CPU is causing the crashes? I'm planning an upgrade soon
