Ok so im running two 3870 in crossfire but now when i try to rotate the screen ccw the screen goes black and PC locksup....as in the mouse goes dead (LED wont light up) & keyboard caps lock LED is dead.
Manually reboot the machine and the desktop is now roated CCW ok
Another thing, when playing Left For Dead, the performance drops to teen fps when i get to end of campains with loads of tree's. This is made worse when firing the gun off (creating shadows all over the place, more work load etc).
Never did this before.
I uninstalled the drivers via "ATI uninstall utility" in Programs & Features
Installed latest drivers but exact same issue. Also my overclocks remains in ATI CCC, which is odd because that doesnt normally happen.
