Running Windows 7 Ultimate. This was an upgrade from Vista Ultimate. I had a couple of problems with Internet dropping unexpectedly and a rogue Vista Service Pack 2 trying to install all the time, but Windows 7 support was able to correct these problems.
I have had a starting problem that I needed to use the Windows 7 disk to repair the start up, but that happened just once. Since then this current problem has happened twice. I come back to the computer after several hours away, the screen was black and I was unable to get the desktop to appear. Moving the mouse didn't do anything. Only recourse was to shut down and restart.
Any ideas on why this is occurring?
