Just bought an diamond radeon hd 4650 (agp) card for my aged pentium 4 system with an Nvidia 64mb 2x/4x agp card. When installed I could not get any video through the card??I replaced the 350w power supply to a 500w power supply per recomendation, same results. Reinstalled old graphics card and works fine. Would like to squeeze out a few more years on this Desktop. Had similar results a year ago with a different video card. Would rather not spend another $40 to have someone install for me, like to learn as i go. Any help, Ideas would be appreciated
