I recently purchased a Zotac GeForce 8800GT Graphics card for my gateway that has a C51G+MCP51 mobo. When i tried to install the graphics card in the PCI-express slot it would not go all the way down because there is a part on the mobo that blocking it from going all the way down. I believe that piece bloking my card is called a compactor. My question is does anyone know a way that i can get around this without having to buy a new mobo? I have a picture of my mobo stored on my computer, but am not quite sure how to post it up.
