I recently tried to install a 6600GT video card, but got no POST, no mouse, nothin'. Here's the thread. I RMA'd the card, but in the meantime, I read that one of the fixes for the problem I had was to reinstall Windows XP. I don't want to unless I know its corrupt.
What I did, in order:
Strange behavior since the defrag step was completed:
-lots of old programs (nearly half) in the start menu are highlited as "new programs"
-lost calculator and solitaire game that came with XP
-DVD's stutter and stop after playing for a while (prob'ly heat related, but..?)
These are minor, easily fixable annoyances, but do they indicate something larger? I've not experienced any other problems.
