I recently tried to do a fresh install of 8.1 Professional from the install CDs. The install process appeared to go normally (no obvious error messages). Although I noticed that the install CD contained an older version of the nVidia driver for my GeForce4 video card. After the install completed, I tried to boot the system. The boot went normally until late in the boot process when the screen flickers and the video driver starts. At that point, the boot process stopped and the screen went black. I tried to boot the system several times with the same results. (I finally gave up and installed 8.0, which which booted successfully.) Has anyone experienced this problem with 8.1 or know how to solve it? Thanks very much for your help.
