I have an Athlon XP 1600+ with an Asus A7M266 mobo and I am having problems with my computer either locking-up or rebooting whenever it is jarred at all. Just stomping near it or turning up my Klipsch subwoofer seems to be enough to cause it to have fits. My vid card is a Geforce 2 MX 400, and my sound card is SB Live Value. Any help would be appreciated, thanks.
