I have just acquired this motherboard in a PC from a friend who gave up trying to install XP. When I try and install XP Pro it get to the "39 Minutes" mark then reboots and it will continue to reboot until I turn it off. I have installed Windows7 Pro 64 bit and it installs and runs fine, I have also installed Windows 8 64 bit 90 day trial and it installs and runs fine. Another problem is that if I set AHCI before I try to install any OS then the SATA DVD Drive disappears and will not boot. Thanks for any help Regards John
