Hi! Can anyone help me please, I have just bought an X700 Pro 256MB PCI-E as an upgrade to my PC. I have installed the card and turned on the PC but I get a 'no signal' remark on my screen. The cable I am using is fine and the card seems to function as it starts to get warm when operating. Anyone have any ideas? Is it a duff card or do I need to do something in BIOS?
