My video & sound drivers are up to date, my computer complys with the minimun requirements, there's no other background tasks running anything else other than system....but the sims 2 university still crashes back to desktop after full screen, but it never used to a few weeks ago and I haven't installed or changed any settings at all recently. Why does it do this?

...And I cannot re-install if required because my original sims 2 is missing and I cannot purchase another.

by the way, my graphics device is SiS M661MX, if that provides any help towards solutions.


thanks for your help.
