Johnathon: just realised I hadn't tried command line. have now and it's
in progress :D thanks

Andrew: All 3 fans work, BIOS is set to optimised defaults (as of this
morning), and ALL the hardware is new (Christmas) bar 2 cd drives and a
floppy. I've hunted around online a bit and lots of people have had
problems with the same motherboard. Graphics card is nVidia 8600GTS
1024mb memory, peak temperature around 50 degrees.

Cheers
