I am running SW 2009 using Nvidia FX3500 graphics card.
As of the other day, my screen locks up during simple command orrotating using spaceball. I can still use my mouse to save and openother windows. This happens less than a minute into a new sessionof SW.
I changed out the graphcis card with an identical card - sameresults no solution
I uninstalled and reinstalled SW 09 - same result no solution.
Dell tech support had updated all bios and other drivers - nosolution either.
The only thing I havent done is change out the HD??

Has anyone else experienced similar issues or have othersuggestions?
I have been running with no problems on this system for 2 yearsuntil thsi week.

Thanks ChrisSolidworksEdrawings
