I'm new to forums and I am having trouble loading win7 32 bit pro on my new acre aspire x3960 desk top. It came per installed with win 7 64 bit home premium and I have bought the 32 bit pro. I have inserted disk and hit f12 and gone through loading off cd/DVD. The windows logo comes up and then it comes up flashing 4 colors horizontal ( red green blue and white) then a grey screen, white screen and black screen and just continues to do this. Can anyone please help.
Ps. I am an amateur I am trying to get this up and running for work purposes.
