JJ2 gives me a blue screen and restarts my computer when I exit the game. It said something about a dll going wrong or something like that. I had to lower hardware acceleration in the first place to make JJ2 run on my new rig.

Specs:

AMD Athlon 64 X2 6400+
EVGA Geforce 8800 GT
2MB DDR2 800
Sound Blaster Audigy 2 ZS

The reason I had to lower hardware acceleration (1 tick) was that JJ2 would lock up during the splash screens (Epic, P2, etc). The game works fine otherwise. I can just alt-f4 if necessary, but I'd rather not have my computer crashing.
