I just finished building my PC, but I can't get a signal to the monitor.

What could be a possible solution other than paying Geek Squad $150 to look at it?

Are you using D-sub or DVI? Have you tried changing the input selection on the monitor? Are you sure you installed the Graphics card in the correct PCI-E slot?
