Help pls ran outta ideas!?

[HellRaiser]

I was wondering if anybody could help me with this problem..
Freelancer was working fine all this time, untill a few weeks ago when i tried to play.
I logged in and flew towards the Jump Gate/Hole, when i jumped, my computer restarts in the middle of me being inside the wormhole...Its really weird because it happenes only to Freelancer..just keeps restarting while im inside the hole.. I tried going inside Control Panel/System/Advance/Startup Recovery and turned off Automatic restart, when logged back in and tried to jump between systems, computer froze at first and than i get blue screen and it begins dumpung physical memory...Again this happenes only to Freelancer. I play other games such as HellGate, Oblivion, Call of Duty 4 and the all require alot more Computer resourses than Freelancer and all work fine.
I tried re installing freelancer and mod..nothing helps...I've been trying to figure this out for the last few weeks and just ran outta ideas...I need help pls if someone knows how to fix this or might have some suggestions

I'm running XP with 2g ddr ram
Pentium 4 2.80 GHz
