I got a new video card from my in-laws over x-mas and it fried yesterday and reverted back to my old GeForce 8100. Everything started to work but in max resolution 1280X1024 (recommended) my screen flashes extremely fast when I swap screens, minimize, load a web page. Pretty much any command that changes the images on the screen.
I updated my driver for my old card, I checked the cables, I have restarted several times. I removed the broken newer card out of my computer. I even put a new monitor on and it was still happening. If I lower my resolution one tier, then the flashing/flickering stops, but any games or programs get an FPS of 2-4 which never happened on this card before ever.
