Sometimes its better to be lucky than good. Taking t-mpg's advice I uninstalled the video drivers in Device Manager. I went to install them when I noticed oops I don't have the disk! What to do? I know; I'll go on line to ATI and download them. But wait, I'm in Safe Mode w/o Networking so no internet. No problem - I'll just reboot into Safe Mode w/ Networking. Shut down, start up --- hey what's going on here? Windows is seeing new hardware. Could it be? Yup, no pause in start up. No warning message. Just a few minutes of waiting and all is back to normal.
Don't ask me what or how but it's fixed.
Consider this one closed.
