I am helping my friend install a new graphics card in his computer. It's working fine, but it won't register that there's a new card in the computer, so we can't install drivers and stuff. Also, he can't get the resolution the way he likes. The card in question is a Geforce 9800 GT, if that helps. Also his "p" key is broken so you have to press ctrl+v every time to write a p, and it sucks.
I probably would've bought a new keyboard before a new graphics card.
What OS are you using? What does it say under Device Manager and Display Adapter?
