I just upgraded from my old Athlon 1400 system with WinME to a new a64 system with WinXP. I'm having trouble with subspace/continuum, it crashs my system. What happens is I'll be playing for a bit then all of a sudden my the screen goes black, my speakers hiss, and my system reboots. This doesn't happen every time, but it does happen often. Any idea what's causing this ? I haven't experienced this type of crash with any other games.
