When I try to boot my Windows 7 Ultimate system it hangs at the screen in the attached image. I never see the Windows logo appear. I was able to setup the HDD externally and run scan disk, system file checker etc on it and to backup critical data because I feared I may need to reimage the system. I wanted to use my Windows disk to attempt repairs but even booting from the disk results in hanging on the same screen. I also tried a different HDD and get the same result whether booting for the HDD or the disk. I also removed the RAM one stick at a time and get the same result. Has anyone seen thsi problem before and do you have any suggestions of what to do to fix this?
