A user on the network, was in e-mail when she clicked on what appeared to be a returned e-mail. She got the blue screen with a message she never saw before, but she didn't write it down or commit it to memory! She pressed keys and alternated between blue and black screens. She tried shutting down, but the system hung, so she left and went home for the week-end without powering down! She returned to the office on Monday morning to discover her system won't reboot and of course after several tries, she calls ME! When windows attempts to start, the splash screen comes up scrambled! All the words are legible, just broken up on various parts of the screen! If I hit ESC to see what's going on, it says unknown error (twice) then it either hangs or comes up with a red garbled screen! Every third time I attempt to start windows, I get the following error: While Initiating IOS Windows protection error. You need to restart your computer or a get a registry error! The splash screen is always jumbled! I was successful with opening in safe mode once, to the point where the wallpaper loaded and then it hung. I have never seen anything like this, and the NORTON emergency disk is not correcting whatever it is! Any suggestions?
