Ok for a while now somtimes My PC will Restart when going through a Jump Hole or a Jump Gate thing. Its been doing it since i got Freelancer. Lucky the game Auto-saves befor it crashes so i can just load up and ill be in the system where I was intending to go.

My PC:
AMD Athlon 64-bit 3200+
2GB of Corsair Ram
nVidia Expert Vision 6600GT
Windows XP Pro (its actualy Legit copy too)

Any idears what the problem may be?
