Hate to be the bearer of bad news, but this sounds a lot like Operator Headspace and Timing error.

Any tech worth a darn would have told you to completely delete the old drivers first (ie. use Driver Cleaner Pro). That will remove ALL instances of the old drivers.

Then you install the old drivers. Plus, it's not the card. By your own post, you said that the problems started after the last update you made. That means it's drivers, not hardware.

Drivers = Software
Card = Hardware
