I have two builds that I just hooked up to my acer monitor (it has a built in input switch button) and can't get a signal from the new vga connection. I hit the switch input button and the screen goes black and says vga in the top right, but then quickly goes back to the dvi connection. The dvi works, and the vga cable is secure at both ends. The vga connected PC does turn on, and though I haven't used it in a month I am fairly sure that all the components are working. I would try connecting the cable to the gpu instead of the mobo but there is no vga on my gpu.
