Prob sorted , yanked the memory stick gave the contacts a wipe fired up and its fine.
Built this particular machine about a year ago,had to flash the bios on the M/B to accomodate a faster CPU, had a few bios probs with it is all, thats sorted now.
Re moving hard disks between machines, not had any probs with that, the hard disk loads a few thing up it needs for the new motherboard I assume, and works just fine, same thing when I returned it to this machine.
Thanks for the help peeps.
