5870 gsod cant fix

Corsair TX850W 850W CMPSU-850TX 12V 70A 24PIN ATX Active PFC 140M Fan Power Supply

ya thats what i was afraid of >.> o well atleast its got a 3 year warranty  

Yep, clearly that is a more than sufficient PSU. So at this point, you need to start swapping components.

fanboy much? I've had dud Nvidia cards as well as ATI cards. I had a GTX 260 that went back for a very similar issue, random reboots, black screens, white screens.

The OPs PSU is more than enough. I have an artifact issue with my 5870 and is actually back to ASUS a second time because of it. I use the GPU stress test in OCCT and turn on error checking. It counts the number of errors that occur and it keeps a constant image that allows you to pick out artifacts when they occur. You may want to try that to test it out. Most likely you will need an RMA. http://www.ocbase.com/perestroika_en/index.php?Download

I guess he missed the card killing NVidia driver a month or so back  

Edit: I love that error checking in OCCT. So jay, was your card even throwing errors at stock?

Yes, it gives a errors and you see little white dots that show up. ALL stock. Once the card gets to 80-82C is when it starts to happen. If I lower the GPU clock to, lets say, 700MHz it goes away. OR if I raise the core voltage to 1.2V it goes away. The memory clock does nothing to solve the issue. Everything was fine when playing games that do not need alot of GPU umph, like MW2 and Left4Dead2. The first 5 months I had this it did not see more than 75C on any game. I played Dirt 2 a little after a few months and that gave a few artifacts but I didn't play the game long enough to care. I then got Bad Company 2 which caused my GPU to hit 85C and give artifacts and at times crash out to the desktop. I didn't run the OCCT before that because I didn't have an issue, which I should have done on day 1 so I could have returned to Newegg. Now I am stuck with ASUS support. Which they are VERY nice always answer the phone. But, I sent it back and it doesn't seem that they did anything to it. I called them and they ensured they would test it thoroughly. I could have gotten an advanced replacement, but there were non in stock. So I'm getting it back Friday so we shall see. The Service report still has the same serial # but I don't know if that means it was just the reported serial # or the one I'm getting back. We will see. If it doesn't pass, I will call again. They told me they do not game test, but have proprietary software and end with a futureMark test. Which never had an issue before anyways.

Ah, I see. I just wanted to check, as I have serious Dirt 2 shadow flicker, however today I just confirmed it is a Game glitch (not driver or card) that came with the patch.

Yeah that is why i always confirm with something else like OCCT. Which makes me angry because apparently ASUS test apps apparently don't catch the issue. I will call them again and send it back on their dime if it has the same issue.

i did the occt thingy and in a few minutes i got 250 something errors it was fine for the first minute or two then it just started going blank and you could hear the fan on my card just die down then restart back up again when the screen came back
said something about 0.71 v or something and the crashes happened about three times over about 5 minutes
