hm... if you don't mind sure, i'm guessing seven just doesn't like the driver

I'm running Catalyst 9.12 on a 1GB GGDR5 4890 stock from Sapphire - everything works fine.

Run a disk diagnostic such as Seagate Seatools, then schedule a check disk run. Then run Memtest86+.

I doupt thats the problem, as I'm running the same RAM stick, and the same harddrive for XP.

Have you made sure that your motherboard chipset drivers are installed?

No unknown devices that appear in device manager?

Have you tried installing the latest Directx 9.0c redistributable?
Download details: DirectX Redist (August 2009)

Lastly, just because an overclock is stable in XP, does not mean it is stable in Seven. Seven is a little less tolerant of instable overclocks

hm.......... does your device manager show any conflicts with the card?

No conflicts, no unknows drivers in device manager 8except a bluetooth thingy), and chipset drivers installed (latest).

Have you checked the Event Viewer Logs to see if there is a faulting module that may be crashing the display driver?

(type 'Event' in the taskbars search and select 'View Event Logs' > Custom Views > Administrative Events)

Look for the driver crash error and see if it points to a particular file in the Faulting Module Path:

No particular file in the Faulting Module Path.. Just "atikmdag.sys has crashed, and has successfully recovered".
