When I restart, the message I get is "your system has recovered from a serious error". Plus, one time it said that messages from my ati accelerator were being misread or something, so it had to reset itself.
My computer is a P4, 3.4 MHz with 2 gig of ram and my video card is a 256 MB Sapphire x700 pro.
The only "different" thing I have done this time is I am using a "glow" effect. I have used the glow before though, but the scene was smaller.
