When I turn it on there is absolutely no signal going into the monitor. It just stopped working one day. I’ve tried replacing the vid card with another just like it. I’ve tried using a PCI card instead. I’ve also tried disconecting everything but the hard drive and still there is nothing. The card is seated all the way in, and the components I’ve used to test it, all worked. Any suggestions?
