re-installing windows vista

Before I finally send this piece of junk back to Dell (minus the graphics card I had to replace thanks to their extraordinary poor customer service) can anyone help with this major pain in my computering side.

Almost two weeks ago my computer crashed mid-game causing me to restart, however windows vista refused to load just sat at the green bar loading screen. I managed to get hold of the hard drive and put it into another system and it seemed fine, so I brought a new hard drive (to avoid losing data) to install windows on thinking it would be easy using the disks dell provided. I was wrong. Vista gets so far and then gives up the ghost the message that "Windows setup could not continue installing windows due to hardware". I've ran checks on ram and all seems to be in order. I've tried following instructions for re-installion of windows but nothing seems to mention this and the error message appears either before or after the first installation.

Any help or advice on this would be a miracle. Like I've said I've been to hell and back with this system and this is turning to be the final straw and I certainly refuse to pay any extra for tech help considering the amount I've already paid.
