I don't know where to post this really, but since I re-formated my harddrive last week all A7 powerd games including my own have started to lag. I'm down to a constant 10 fps in all applications.

Before the format I had windows xp x64 now I have xp pro.
Maybe this have been a before mentioned problem but I've serched the forum with no luck.
What can I do ? I'm at a loss here.
