I may have to drive tweaking that then, since it just happened again, and it happened after the comp was off for a whole night, got turned on, and then happened in about 15 minutes, so I can't see it being a heat issue.

Yeah, something must be lacking somewhere. Or something's not stable somewhere.

I just had a similar issue with the drivers crashing on me, except that my PC would not blue screen or reboot. My GTX 285 OCX comes factory overclocked to 702/1332/1584 and the OCCT GPU test would not even run. It would crash the drivers in 1 second. The Crysis benchmark would crash the drivers after a few tests. 3DMark vantage was stable. Anyways after I got back from work yesterday. I removed the old drivers and used driver sweeper to clean traces from the old drivers and went to the second latest official drivers. I underclocked the card probbaly 3% and was stable and OCCT was running. But OCCT is so damn complicated. Something that works now error free, will start giving you errors some other time and then it would crash the drivers again even when underclocked a little.

So again I got rid of the drivers, used Driver Sweeper again and CCleaner. This time I went to the latest beta drivers and left the clocks on defaults. OCCT gives a lot of errors within the first minute and it doesn't even let the card get that hot. Sometimes it's in the 70s and it gives errors.

So I said the hell with OCCT and benchmarked 3DMark Vantage and benchmarked Crysis and it seems stable at the default clock speeds. I'm sure this card just comes overclocked to the max it will go. Maybe even a little too much. It probably was a refurb card that someone else had returned. But I have waited over a month to get a working card from BFG so I think I will just keep this one, otherwise this would be my 3rd RMA. Unless later on I start seeing artifacts and locks up when playing my games.

My idle temp is 48C and max temp is 87C

I had a similar problem with with my 8800gts where I would get artifacts when watching movies. I'm not too sure what the exact problem was, It might have been my Rocketfish 700W psu, but yours is 850W so I don't see how that could be the problem. Maybe even try to run a memtest

Or one of the cards is simply broken, which would perfectly suit the discription in the first post.

I have the same problem with my ToughPower 1200W and HD 4850. And the only system change before the BSOD's is Win 7 x64.

It happens while watching video online or off, no matter the OC, drivers, player or codec used. And my max GPU load is 48ºC..

I agree and think its possibly heat issues, have you a fan controller installed like evga precision or riva tuner, either of them will allow you to set up hotkey fan profiles you can select for different staged fan percentages so you can chose the one appropriate to your needs ie 100% for gaming, 90% for less strssful games, 80% for folding etc etc, or you can set them up to automatically to go to certain settings from the initiation of certain .exe, like i have it set to go to 100% gpu fans when i click on the cod4 .exe
hope this is of some help

Well I've tried upping some system voltages, just about anything I could, one at a time, it hasn't made anything worse, but it hasn't fixed the problem either.
I know it has to be the Nvidia video driver since when I reboot the comp, vista comes up with reason for crash and what not, and it tells me its a problem with that. Is the 64 bit Nvidia driver just not stable or something?

Ghostleader

Sure it can be the driver but other things can make it crash.

Do you run any OC at all when this is happening?

Which Nforce driver do you run?

You run a 780i, manufacture is who, Evga, XFX, Asus or other?

Which bios do you run?

Ok a lot of questions, I'll try to answer as many as I can real quick
Thanks a bunch for the help btw.

I run EVGA Precision, everything is default right now, except the fans, I have them cranked up to 80%

I use driver version, 8.15.11.9038. (I just use driver detective to update my drivers usually and that's the one it's given me.)

The 780i is EVGA.

The BIOS is Phoenix Technologies, LTD.
Version 6.00 PG

Also it doesn't seem like the cards get hot before the problem occurs, but I'm not 100% sure since I'm not looking at a temp when it crashes and trying to do anything once the problem happens is impossible.

Maybe one of the cards is broken, I'll try running each one individually for a bit and see if they both crash or its just one.

I'll also try some underclocking since Saulin was saying they come pretty OC.
