I am helping out a friend who has a -- Alienware area51 tower. It had Windows XP on it And I am trying to put Windows7 on it but for some reason this unit does not want to be friendly to me on this. This is my most diffecult unit I have ever worked on.

Here is what I am working with does anyone have any ideas so I can get this person up and running.

alienware area51 big tower

4 gigs of ram

intel D975xBx motherboard rev 304

core 2 duo 1.86ghz e6300

it was set up as an raid but I have never worked with raid and my friend just wants his tower to be like other desktop towers. He does not play games anymore but this unit is still a great unit and really does not need to go get a new pc.

Are there any settings on the motherboard that I need to change. It does support 4 sata drives.

Help!!!!!!!
