hey there i own a MSI MS-7236 with Intel Pentium D 940 3.20GHz CPU . i updated the BIOS using the live update application that comes with the mobo cd. and it updated to version 080012 04/03/2006 also updating my ethernet drivers and some vga thing. i had to reinstall xp because of a virus infection and now it stops responding a few minutes after i log in.

does anyone know where i can get the factory default BIOS? all i know about the version is that i was from 2004
