Hi, I've booted off the flash drive went through the text mode(it saw the HDD) then GUI and when it was supposed to start Windows I saw the start animation and then the PC rebooted itself. I couldn't install it this way so I tried installing from a cd, with the exact same outcome. Next step, I disabled AHCI and used IDE in BIOS and install XP from the CD which worked. Now I have to dig to find drivers since XP is not supported anymore by ASUS. Thanks, T.
