[AT] OT - computer problem

[Mike Meulenberg]

Since it's slow, I have a question for some of the computer gurus on the list. I have a computer in my shop that I use to store service manuals, and to look things up online without having to track grease into the house. It's also used to list to music online. Yesterday when I turned it on it seemed to be running slow, but did finally come on. Windows did some kind of update, then re-booted the system. When it came back up it would not load windows. The fans are running at full speed and the screen is black, no blinking curser or anything. I cannot boot into safe mode. Any thoughts?
Thanks,
Mike
