I have a MSI R6950 Twin Frozr II that's been giving me problems since I got it in Feburary (I got it for free used and the warranty is over.)
I've baked it in the oven twice. The first time it fixed it and it worked fine for about 2 months with little issues (occasional artifacts, screen splitting, or crashes, but nothing too bad.) Last night I baked it again it worked fine for about 2 hours then started giving me all the same problems I had before only more frequently (At first my screen would split in half while gaming and stay there or start spazzing out with artifacts and splitting then going back to normal several times a second. To fix this sometimes I could just disable the second monitor, and it'd fix it, then re-enable it, other times when I did that the screen would go black and I'd have to restart my computer and then it'd work again. Sometimes I could go hours without any issues, other times I'd fix it and it'd happen again in less than a minute, sometimes only a couple seconds.)
Now I can't even log into Windows, the screen instantly goes blank or I get vertical lines across the screen once I finish typing in my password (either a combination red and dark red, blue and dark blue, green and dark green, or gray and black) and I have to stun down my computer via the power button.
The only way to use Windows is to uninstall the driver in safe mode and use the generic driver which I can't game on and have to use a low resolution. I've tried installing 12.3, 12.4, 12.10, 13.1, 13.2, and 13.4. Whenever I try a different driver I boot into Safe Mode, uninstall the driver in Device Manager, boot into Windows using the generic driver, uninstall the driver in Add/Remove Programs, boot into Safe Mode and use Driver Fusion to remove any left overs, boot back into Windows, install the new driver have it work fine (Aero works and I can run 1920x1080), then I restart like the installer tells me to, and it'll crash as soon as I login.
It's weird how it works fine using the generic driver (other than the downsides of using the generic driver), but as soon as I use the ATI drivers I can't even log into Windows.
Does anyone have any suggestions to get this working? I can't afford a new graphics card right now. If you need any more information or this was a bit confusing let me know.
