My monitor is going barmy

Its a HP pavilion F1523 and everytime on vista when i change users or log on the screen flicks off for a second then back on for a sec then off again and the only way to stop it is taking the power lead out and sound cable and making sure the off button is off on the monitor.

I also got a pop up saying a display driver managed to turn the screen back on wtf?

Some matrix lines keep popping up randomly as well. Its not a virus as i have scanned.

Does anyone know what is wrong with it?

first off try updating your graphics card drivers
secondly if you have an add in graphics card rather than on board try reseating the graphics card
if that fails it could be a failing graphics card (even onboard graphics can give up)
let me know how you get on
also is your monitor set to its default resolution and refresh rate
