athlon 1.4
256 mb
80 gb
win xp
gforce 2 64mb

having problems playing bhd. everytime i join and play for about 2-3 minutes, pc automatically restarts. it was working when i had win 98 but now it doesnt. asked around and some say it was memory leakage but not quite sure. could it be my onboard video driver since i haven't installed driver or doesnt matter cuz im using g card?

Check your ram. That fixed my reboot problem.

could it be possible if i overclocked my ram or cpu. before i had 256 ram but then i got a 512 and used the 512+128. after that i used a dianosis program to check what my max ram is and it said 512. so i took out the 128. using the 512 it kept automatically restarting w/o using any programs.but when i used the 256 it works fine. so could this be a problem.
