UPDATE:
I received the NEW PSU today, so thanks to EMERMAX Support for their help
I've now managed to get Windows XP installed but each time it restarted I had to keep clearing the CMOS.
I've flashed the Bios with the updated 1 (beta11) thinking this will cure the problem, but no matter what I do I have to keep clearing the Bios to start the computer up.
I'll give ABIT Support a ring tomorrow and hopefully they will be able to help me.
Sooooooo..........
