Check this thread. I'm gonna try running it without a case and with some extra fans.

I have the same problem, lockups and bluescreen (yes, only blue and no dumps) in Windows XP SP1. Happens 95% of the time when i play Unreal Tournament 2003. I have not yet had an uptime of more than 4 days on this Dell Dimension 8250. ATI Radeon 9700 Pro with newest Catalyst drivers.

Can it be the 350W (right?) power supply that is too weak the hungry ATI card?

I have Windows ME and Dimension 8100.  I loaded a CD Burner about four months ago.  I have turned it off to see if it stops the freezing.  However, I do not know if this is the cause or not.  I also have MSN 8.  I do not get any messages, it just freezes up.  I do not think I had this problem prior to MSN 8 or the CD Burner.  Even if I Ctrl Alt Delete, it freezes up and I have to shut it off at the tower.  Isn't shutting down that way hard on your system?

Just to update, I haven't played any 3D hungry games in weeks so it seems to be related to the ATI Radeon 9700 Pro and/or drivers. My current uptime is 10 days and counting...
