i bought a nvidia fx 5200 stuck it in my motherboard etc,then installed the software drivers then it said restart i did and nothing has changed can anyone help this card cost me £50!

Hmm, i also have a 5200fx. I hate my 5200fx, it might just be your card man, mine stinks.

Otherwise i would try reinstalling widnows and putting all your drivers back on, make sure your computer is running from the 5200fx and not trying to run on your previous card.
