I have the MSI HD6850 card, bought last June. I've been using it since then, no major problems, most games run on medium/high settings fine. About a week back, some games started to freeze between gameplay, and then after a few days, Win7 would hang whenever I'd be using it, games running or not. I cleaned out the PC, swapped the single RAM into another slot, but it'd still hang after a few minutes, randomly. I booted into a live Ubuntu CD and it got stuck there too. I removed the card altogether and used the PC, and it ran fine. Now I read today that the MSI 6850 has a history of freezing, and the way people have been able to fix it is by underclocking it to 1005 MHz. I tried that method today (did it with MSI afterburner), but now sometimes the PC doesn't boot (get past the POST screen), or when it does, it hangs on the desktop login screen. Is there anyway I can rollback these changes to default values now that my PC doesn't boot into the OS?
Thanks a bunch.
