Getting frequent AMD driver Crashes and BSODs on 6990. Used to run perfectly.

Well I've got a 6990m like my signature says. Been running it without issues since launch. I undervolted to 1.0v and ran great for weeks w/o issues on CAT 11.8.

Starting the other night I have been getting AMD/ATI Driver crashes ("The ATI Driver has quit working") while playing Deus Ex Human Revolution (great game BTW) and also getting freezes during Google Chrome use. I reverted back to the original GPU voltage, but have the same issue, so that isn't it (and I didn't expect it to since it has been running great for weeks). I then updated from 11.8 to 11.9 Preview, hoping that might help (which I know it shouldn't since this issue really came out of no where, I had not done any software or hardware changes since getting the laptop and installing all my upgrades). The crashes still happened with 11.9 preview drivers. Then I uninstalled Catalyst, ran driver sweeper multiple times along with registry sweeps, and reverted back to STOCK Dell 6990m drivers, but I am still having the same issue.

Now I see possible solutions as....

1) Reinstall Deus Ex, but I doubt it is really the problem.
2) Reinstall Windows which may fix it.
3) Get a new GPU if the above doesn't work, I have complete care so I'm not worried if it goes this route, just hate the time consumption.

What am missing here? Any ideas?

 

Keep in mind I'm an R1 guy but that really sounds like a corrupt windows install to me....at least given the t/s you've done so far. If you don't have a backup set...then a clean install is the way I'd go. That really doesn't sound like a hardware issue to me. I'm jus' sayin'....

 

I'm leaning that direction also. I am just hoping to avoid it if possible.

Any other ideas?

If not, I will reinstall windows on Thursday.

 

If you have a spare hard drive, just do a clean install on that. If it doesn't work, then you still have your old install setup like you want it.
