The problem I'm having now is that when I tell the computer to go to sleep or shutdown it will for a moment... only to then re-start. Occasionally Windows will tell me that the computer was shutdown improperly upon restarting.
I have adjusted the power settings with no luck.
I have returned the computer to an early restore point. It corrected the problem... then it it started again (before the updates were installed.)
I have checked and my BIOS is the latest available for my computer.
I have checked Nvidia and downloaded a new driver (NVIDIA MCP55 Package Driver V1.08) and that corrected the problem. I put the computer into sleep mode several times and shut it down to make sure it was fixed. It seemed like it was.
A few hours later I decided to try again. Lo and behold sleep mode caused a re-start. During that time the resolution on my computer was reduced while I played some games. It also switched the color scheme to basic because ZSNES isn't compatible with Aero. That is all that happened during those few hours. Nothing else was downloaded or updated so I am at a total loss as to what is causing the problem. It's obviously fixable as I've managed to do it temporarily twice.
Any suggestions or things I haven't tried? The good people at Dell (what a joke) spent two hours fiddling with the settings only to conclude with "It isn't a hardware issue. If you want software support you'll have to pay for it." This isn't causing any other issues but it is driving me crazy.
