I recently had a dual PCB GTX 295 and I never had any driver problems :S
Have you tried it on another PC completely separate?
Have you tried playing with a clean installation, with nothing but the games and drivers?Anyway, bad time to get one, with the DX11 issue you'll go crazy. Still, great card, never disappointed me.
If it weren't for hackintosh I'd still have it.
I already tell you, I've done that with all of them, Windows 8, Seven and even some Vista.
In Win 8, the GTX 295 drivers go terribly from 306 onwards and you can tell there are compatibility issues or who knows what, and that's the unfortunate part.
I've tested the card on other PCs and even in a store, with mixed results, in some it crashes and in others it doesn't, always depending on the OS and the driver model.
Look today, I took and installed Seven ultimate 64 on another hard drive, only drivers 314, plugins and libraries and a couple of games, and not a single glitch, without touching the fan or anything, all ok.
I think that when I previously tested the 295 with Win 7, drivers 314 didn't exist, and it's likely that's why it crashed too and that Nvidia has fixed it with the latest ones.
In Win 8 all versions, which is what I have at the moment, both 32 and 64, if you install drivers higher than 306.....you go back to the blue screens.
I have no choice, I have to come to the conclusion that, it's the drivers, basically because the card works with certain drivers and not with others within Windows 8.
So finally I went back to my Win 8 enterprise and left the drivers 302, which after a few hours of testing with Rfactor, Shift2, Resident 6 or Fifa, work well even without touching the fan....
If you put other drivers higher than 306......you need to turn up the fan, so it doesn't crash, and others directly just freeze.
Very good work by Nvidia ^^, yes sir.
So thanks to everyone for the cable, the issue is solved, by the way, the card's bios, was the last existing one.
Regards!
