First system build. I've installed all the hardware. The motherboard is a P5KPL-CM. When I turn on the system the monitor is blank and I don't get a BIOS message or anything... it's just blank. The monitor does have power to it. The monitor is hooked up to the VGA port. Should it be hooked up the the video card port instead? The P5KPL-CM has an LED on the motherboard and when I power up it lights up green. What am I doing wrong?
