Hi im having problems with my video card i cant find one?

how do i go about geting a new one or to update it but i cant find it to update it|||If you don't have a video card installed in one of your PCI slots, chances are it's onboard. In which case you just need to buy one, maybe download the driver for it, and install it in your PC. Follow this guide: http://www.directron.com/howtovideo.html
