I will give that a shot. I must also correct myself from my original post.
Only 1 of the user accounts shows the crashing explorer behavior. The rest are fine. They are just stuck in the Classic mode.
Confirmed that it is indeed explorer.exe crashing. I watched the Task Manager window for a good 20 minutes. When the flickers happen, explorer.exe dissappears from the list and almost imdeidatly reappears. When this happens, system idle process goes from 99% to around 70%, explorer.exe disapears, comes back at around 30%, and then system idle goes back to 99% and explorer to 0%. This all happens in the blink of an eye. So, on one user account explorer.exe is dying and coming back every 30 seconds or so.
Also, in safe mode, I get the same exact thing as I get in normal mode. Explorer.exe, flickering, the whole works on that one account. The rest of the accounts are fine in safe mode.
I will update the video driver
and report back.
