Walt,
I was in this computer yesterday, updated Video Drivers got it semi working, but now hes having issues again. I have asked them to download and run this Malware scanner to see if that is creating the delay, as something is in the computer.

This is pretty good about cleaning up systems, just takes some time for sure! I just figured I would post what I had already done on this system, and it has all the Windows Updates.
