This is my motherboard:
I recently bought a ATI radeon 8500 LE (AGP 4x), and took apart the computer and put the video card in a slot next to 3 other white slots. It seemed to be the exact fit, and when I turned on the computer everything displayed smoothly. I tried using the CD that came with the card to install everything, but it says it cannot detect the hardware. But after some research I found out I had to disable my ONBOARD video card, but when I go to BIOS setup at boot up there is no option to do this. Also, I tried uninstalling via device manager, and my SiS 650 video card seemed to be gone.
I am utterly confused. Can someone help me out?
