Windows 7 install blue wallpaper hang

My windows 7 installation on my new system won't even start. It goes to the black screen saying "Loading windows files" then passe "Starting Windows", but then sits at the blue wallpaper installation screen with the mouse able to be moved. Any ideas?

Mobo: Gigabyte GA-EP45-UD3P
CPU: Intel Q8400 2.66 quad
RAM: Samsung 2GB (2x1 GB) and Crucial 4GB (2x2GB)
Video card: ATI Radeon hd 4870

I'm trying to install 64-bit from CD, and I've tried putting my SATA cable to the dvd drive in every sata port.. tried all ram seats/combos.. anything else thats known with this board? EIST and C1E are turned off as well.

It does take awhile to get past that part sometimes.... how long did you wait?

Potentially yes, but I would first create a bootable Windows 7 flash drive and install from that. The install should take about 15 minutes. If it still sits at that one part for 10 minutes, consider that you may either have outdated SATA drivers, a failing hard drive, or bad ram.

Thank you both Prophecy/Heaven, the waiting was worth it. After about 30 minutes, my new system is up and running and I'm currently installing drivers/software now. I appreciate it so much, I apologize for such a stupid question. A huge difference before from a 1.8 dual core with 2GB ram!

And yeah Heaven that did happen to me, luckily I had my laptop open and checked back here when it did happen
