Are you installling from Genuine windows discs or ones you`ve burned yourself?
So theres the possibility of it being a bad burn, rubbish quality disk, did you buy them from ASDA?
No harm in burning another disk to find out.
shot in the dark but have you tried re formatting the hdd. if you did a small part of the install there may be files on there it's not expecting?
The reason i ask is i had the same problem yesterday. Tried to do a clean install, with a new LG optical drive, using a copy i made on another drive. You can either try burning a new copy with new drive or rig the old one up and install from there.
I wouldn't rule out a bad disk.
I've had install problems in the past. It was a combination of things, so don't blame the mobo just yet.
How long have you waited at that screen?
Is the keyboard responding?
You tried opening and closing the drive again?
You tried the SATA ports in other configurations (AHCI / IDE)?
You tried booting from optical without the hard drive?
You tried booting from USB?
You tried swearing at the screen?
I only have an external usb hard-drive and iPod Nano, don't think either of them will work.
No neither of those are any good. Pity.
Have you tried reseating all the cables, and clearing the CMOS. Then leave defaults (except time/date) and try a fresh install.
