My computer is an intel quad core 6600 with 4gb ram. Currently it has WinXP 32bit running. I have one hard drive which has two partitions (c and d). I've backed up all my stuff on to d and I wanted to install Win 7 64bit from scratch on the C partition. I stuck the Win 7 DVD (full, not upgrade) and it happily boots up. It completes loading the windows files and then "starts" windows. The light blue wallpaper appears and a mouse pointer appears in the middle of the screen. I can move the mouse pointer around but this is where everything stops. I've waited for a while but the installation does not proceed past this point. Any ideas why this is happening? I'm planning on copying all my files to an external drive and formatting the disk and trying again. Not sure if this will work.
