My computer screen flashes ADJUSTING continously ....NON STOP?

Q: As soon as my computer is on, the screen has a little white box with black letters that say ADUJUSTING flash non stop..It will flash until I turn off the computer . I don't know what to do. I changed the moniter on the computer to see if it would do it and the other moniter didn't have this problem. Once I put this monitor back on the computer the same problem persists. Please help. Thanks. P.S. Tried changing settings in display ( control panel) but nothing worked. Something I changed did make it stop flashing but then it started a couple minutes later. It only stops flashing ADJUSTING when I open up my Norton Antivirus.

A: It sounds to me your hertz rate is set wrong. Ie it sounds like it trying to run your monitior at 70 rather than 60. By selecting the correct monitor from the monitor options in windows should stop this.
