This system worked fine, But then I got a MSI R6950 Twin Frozr III and I haven't been having very much luck with it. Upon installing drivers (I have the latest 12.1 preview and have tried 11.11) and re-booting my login screen looks like this:
Then when I do login the screen goes black and I have to restart. Safe mode works fine. Is this a card or driver problem?
I should also say that everything up to the login screen looks fine as well.
1) Uninstall your video drivers. Then reboot and run Driver Sweeper (free program available for download) and clean out any remaining AMD or NVidia video drivers. Reboot a final time and reinstall your 6950 drivers.
2) If you still have the same problem, try the above but use the previous set of AMD drivers.
It honestly sounds like a hardware problem, but if the above steps (can be done in about 15 minutes) don't work then RMA the card!
