Start Menu Constantly Flashing

Post the list of hardware. Is it a laptop or desktop. You ran scan how? does the keyboard work?

Sounds like a keyboard fault at first glance is it USB keyboard if so unplug it and see if the menu stops opening.

You know when I first had this problem I searched Google and found a half dozen forum entries of people with the same problem and no answers.

I can't believe it is something as simple as the keyboard but by golly it seems to be the problem. My computer is a pc with a wireless mouse and keyboard. Simply unplugging the keyboard didn't do anything. I went in to device mgr and uninstalled it and then rebooted. Presto, no more flashing neon sign.

Thanks so much!
