So my friend has a desktop that has no signal when plugged into a monitor. She said that it was a video card problem. The video card's (ATI Radeon HD4350) VGA and HDMI are giving no signal, and the onboard video memory is giving no signal. Could this be a motherboard problem? If its the motherboard that is also giving no signal, could it be another part causing the motherboard to malfunction?
