I'm having trouble with every AMD driver except for the specific 13.4 7790 driver. And even that is not working 100% in all situations. First, specs:
AMD Phenom II X6 1055T - not overclocked at the moment
Asus M4A77TD Pro
4 x 2GB DDR3 1600
1 x OCZ Agility 3 240GB SSD
1 x WD Caviar Green 2TB
Corsair VX450 PSU
PowerColor 7790 TurboDuo 1GB
Win 7 64bit
Problems with 13.4:
Games work fine, but Firefox seems to encounter graphical corruption. On some pages, but not all, small black rectangular boxes appear on about 10% of the page. Moving the mouse over the boxes clears them, although they can reappear. Also sometimes the display driver crashes and recovers - never in games though.
Problems with 13.9 WHQL:
Often blue screens during installation of the driver. If installation succeeds, on rebooting I am told that no compatible AMD device could be found, and the display reverts to non-Aero. Very unstable. Did not get as far as testing games, since no videos work (not even youtube using the flash plugin) and neither does Aero.
Any suggestions? Could it be a hardware fault?
