okay, i first had a pc with windows 2000 with 64 MB RAM. so i installed win xp, and then everytime my computer crashes... so i went to the store and bought 128 MB extra, so now i have 192 MB Ram. my computer doesn't crashes all the time anymore. so when i play 3d games, my computer reboot it self autmomaticly, so i went to the store again, and bought a nvidia geforce 2 mx/mx400 this time.. well my games did get faster and all kind of stuff, but my pc still automaticly reboot it self. and it's keeps annoying me, so pleasee, can anyone help me?

HI the 3 most likely problems 1) power supply 2) heat 3) the original ram could be bad try #3 first remove original ram and place new ram in its slot. be sure power plug is disconnected.

well... i think that the problem is solved now, it doesn't reboot itself anymore. but i stil got 1 problem. when i play gta vice city and after a while, i hear a 'ding'-sound and the game freezes. i think the could be on the videocard i last bought. could you guys help me hear too? or have i go to a special gta-vc-support forum?

sorry for double posting... the 4th line should be: the game freezes. i think the problem could be on the videocard i
