Several Programs Crash on Startup After New Driver Install!

[Baasha]

As the title says, I just installed the new beta drivers from nVidia (301.24) for my GTX-580 Classified 3GB GPUs yesterday and although everything seemed to go through fine, I am not able to open/launch several vital programs now!

Programs such as Sony Vegas Pro 11 x64, Premier Pro CS5 etc. crash at the splash screen with an "AppHangB1". iTunes opens and works fine but when I close it, it too crashes saying "iTunes has stopped working". Photoshop CS5 x64 does the same thing.

All these things happen in Surround mode (I'm running 3 monitors in nVidia Surround). When I switch to a single display mode, all the programs launch fine and work without issue. So I know it's something to do with the Surround mode.

The really aggravating thing is that I tried to uninstall the betas and revert to the 296.10 WHQL drivers and that too has the same problem now!

It used to work perfectly until I installed these worthless beta drivers!

Please help me fix this problem as I need Surround mode to be able to work on my stuff in these programs. That is whole reason I got multiple monitors to begin with!

Here are the details of the problem:

Please help me figure out how to fix this issue!

Just a guess, but perhaps reinstalling Adobe Pro may help as the beta could have corrupted it, then reinstall the 296.10 drivers as well as any others you need for the application (?)

[Tomken15]

Forgot about the old standby of a restore to an earlier point which usually resolves most problems and prior to downloading any betas, it's probably a good idea to create a restore point in case something like this happens and then you may not have to back so far.

Go to device manager locate your display adapter right click on it then select properties then drivers then select Roll Back reboot.
