I've also seen threads (@tech hq iirc) about a users PSU not being up to snuff for his card, but instead of crashing, the games minimized....
Just banging out ideas for ya...that would drive me batty pretty quickly
I havent tried playing them windowed, could try installing DX again though.
Using Zalman 850W PSU which should be more than enough, was using HD5870 Crossfire before this so I don't think the PSU is the issue.
