Hardware issue installing Win7

Hello all, any help would be much appreciated!

Corsair Dominator 6GB DDR3
WD Caviar Black 640GB

I am trying to score Windows 7 Pro64bit over my already existing Windows 7 installation just to be able to do a clean install. I built system this around 6 months ago but I am having an issues installing Win7 again. I insert the disk and it loads up and before it gets to the installation screen it just locks up and i cant move the mouse or the the keyboard. I've even waited about 10 mins to see if something happens. THis is what it looks like:


So I swapped the cdrom drives to see if maybe it was having a problem reading the disk but nothing. Then i tried a different win7 cd and still no good. My next thought was to check the ram with memtest 86+. A question was should I test each stick individually or all 3 together? Any other suggestions on how to get this installed would be greatly appreciated.
