I just installed my new ASUS P4P800SE board last night and it seemed to boot up fine, i was able to format my drive and reinstall windows XP home no problems. But my system is not detecting any of my devices ie, graphics card, sound card, modem, network card - nothing!!!! I have switched off onboard audio in bios and there doesnt seem to be any onboard video option with the mobo so i cant switch that off. Is there a bios setting im missing here, or something else?!! please help, im absolutely mystified by this.
