you dont have a memory stick or external hd plugged in?, if not delete the x drive when installing, it could be like i said in my first post
Only things plugged in are montor + mouse/keyboard.
Try using different cables if you have them spare, a different optical drive or using different ports on the mobo if there's any spare.
Just trying a re-install using different SATA cables and SATA ports on the mobo. Unfortunatly, I haven't got a spare optical drive to test with. I'm using an Asus Lightscriber, brand new (as with everything in the build) puchased a week a go.
Hopefully it will work this time.
Thanks for your help guys, I really hope I can get this working or my investment in a high end rig will be worthless
