As of recent, my monitor has been flickering every once and awhile. It has never done this before, but I can see the screen flicker bigger for a brief moment, and then flicker back. Its like the monitor is pulsating or something. I was using a Default monitor as the monitor type, but got and installed some montor drivers for my monitor (AOC Spectrum 5VLr). I was running at 60 Hz, now I am running at 70 Hz, but it still flickers. Any suggestions? Is it time to invest in a new monitor?

I should say that to me all monitors flicker running them that slow. 85 Hz is a minimum. Then I know that I'm pretty sensitive for this (f eks while going to the movies the picture always flicker while most other says they have a steady pic).
But 60 Hz, that can't be sane and usable onlu running 14" or smaller I should say. Maybe save money and buy both a new screen and graphic card.

try your degaus button if you have one, should release all the extra "stuff" hanging around It may straighten things up..
