I just turned on my PC and I got a 'RGB no input signal' message on my monitor. So I plugged it directly into the PC and it worked, however when I plug it into the GFX card I get the 'RGB no input signal' message. I am a complete noob with PCs so I haven't got a clue what to do. If it helps my GF card is a Nvidia Gforce 7600 GT.
Please help...
