Well, I used to have a Geforce Fx 5200 256mb Card. I just decided to update to a Geforce 6200 512mb DDR2 AGP card, but ever since I did that I have been having major video problems. I cant play my games at all now, it worked fine earlier but terrible fps, I have all the requirements of the card so I am wondering whats the problem. It kind of bugs me to, because I had to go out and buy a new power supply but I decided to buy a new case with it but either way the thing doesnt work and its very annyoing. I use a Hanns-G TFT LCD 19' Widescreen Monitor. Specs of Monitor also this is where I orderd it from: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1828823&Tab=2&NoMapp=0

All the Screenshots flash the colors seen also.

Install the latest drivers from Nvidia and maybe increase the refresh rate on the monitor if not already set to the highest. also check color settings for it I dont know too much about hardware, but im just sortof tossing out ideas. The monitor might be set to a low fps or something.

It looks as if your card's font drivers are messed up. You could do what mikeanddike22 said, or you could just backup and reformat/reinstall, which you probably need anyway.
