HELP! having trouble since updating my Mainboard bios...:-( ASUS P4S800D hadn't updated the bios since initial install from MB CD. (Bios version 1005.002) Went to main ASUS site and downloaded update 1011, but ever since then PC is wieding out! now when press shutdown, hybenate etc. it restarts...tried to rollback to older bios but have same problem also the CD Rom and DVD rom are not responding anymore (unless I go to their properties and press "populate"?) Any help...much appreciated!!
