I am having a problem that did not appear till I installed this graphic card.  I upgraded from an fx3800 to the 5000 and thing's went smoothly for the last month or so, but now when I really start working solidworks hard(large assemblies, CFD, multiple windows) the screen turns red.  Which eventually causes a blue screen of death, now I can still move my cursor around so it doesn't fully lock up my system.  I was blessed with a error message once or twice that said "The nivida openGL driver detected a problem with the display driver and is unable to continue. the application must close. Error code:4".  I have tried the driver Solidworks specifies, tried the driver that came in the box, and even tried the driver on Nvidias website and NO change.  I have a dual monitor setup, 16gigs of ram, 2 quad core processors 2.9GHz I don't believe these are the problems since the other card works pretty well.  Does anyone have any suggestions?  I have a call in at PNY but I don't think they know what's wrong either.
