get the bios if not already:
GIGABYTE - Support - Motherboard - Utility
I am not responsible for any problems associated with the above
for kicks and if you want too...uninstall all hardware
then reboot and install the 3
sp3 is still beta but I downloaded it and installed it on 3 xp machines, works fine...you could dl and it might not work for you...so you'd know that it might mess up your system when sp3 goes final. lol
when and if you do the above bios (if needed) make sure to reset your system to default prior, flash, restart, if successful, oc again
