This evening I started up FS2004; within ten minutes a strange flickering pixelated look began rippling across the screen.  Getting worried, I quit the sim and restarted my computer, noticing that the pixel effect was beginning to affect my desktop.  Computer reboots, I get to the XP password screen- and the whole thing freezes solid.

I remember reading something about this in the FS2004 forum, but I can only vaguely recall what the problem was (overheating, drivers?).  I just picked up a new 9800pro, so if it's the card I'll puke.  Any ideas?  ???
