There's not much you can do dude - why? Because you're victim to
this problem - I've outlined some tips below but with the problem in the article it's unlikely you'll get to eradicate the problem.
Try rolling back drivers - as Boris recently found out on GD by me, the latest drivers aren't always the optimal one's for your card - try using detonator 4x (ie: 45 etc.) drivers and test each one. Try downloading
these drivers.If that fails then try detonator drivers - v. 29.42 - they are guaranteed to work
If you get the black screens it could be that your mobo drivers probably needs to be updated.
