Okay, so my mom bought a popcap game (Mystery P.I) and it froze the PC (Black screen, couldn't alt+f4, alt+tab or anything). So I took the advice of Popcap help. It told me to update my video card drivers and sound card drivers. So I did just that. I updated them a few minutes ago, restarted and all. Then when i went to DXDiag, it showed me that my video card update date was 17/10/2010 (I updated it then as well) and my sound card somewhere in '09 when I clearly updated them today. This black screen issue has happened for MANY games and it's a pain to me and the PC to hard restart by holding the power button for a few seconds. I think I made a thread about this black screen issue before, but I must ask again, is there some way to address this issue? I doubt customer support will help, but I've sent a ticket to them. What I'm really curious about is what causes these black screen issues for many games, since I ran every other Mystery P.I game fine, except for this particular one. Yes, I reinstalled when it didn't work, and still no luck. If anyone needs a DXDiag of my PC, I'll upload it later when I get a chance to use the PC again.
Have you considered right clicking the .exe file, right clicking and trying to run in a 'compatibility' mode, just to see if that works?
