I have this computer at home, its a P4 2.26 with MSI board, i recently put my 9800 pro in it, and when i play BattleField: Vietnam, it reboots by itself a lot, i mean everytime i get in it will reboot by itself, i just had a fresh installation of windows XP, it still does the samething, i'm wondering what could be the problem? i have only 256ram on this pc, it seems it loads the game pretty shitty and the HD's noise is loud.
