part way through playing ep 3 my machine Blue Screened. When windows rebooted it said the problem was caused by my graphics driver. Now whenever I launch the game all the models appear to be not fully drawn (some polygons are there, but some aren't and they flicker). I've tried messing with the graphics settings, reinstalling the game, reinstalling my graphics drivers, and even starting a new game to no avail.
Windows XP Pro SP3
Intel Pentium R 1.6GHz
ATI Mobility Radeon 9200
I realize this system's on the minimum spec side of things, but everything was working until the crash.
