I have just recently built a new computer. I am about positive i have every cord plugged in the correct spot, but i am having this odd problem. Upon turning the system on every thing powers up and will be begin to work, the processor and video card fan start spinning and the hard drives does the normal clicking noises etc etc. Before you plug in the monitor cord to the video card you see the normal " no signal" prompt on the screen, as soon as you plug the monitor in the screen just goes blank. It does not show the bios or anything. Just a blank screen as if it does not receive any signal, but the video card itself is running(the fan).It will do the same thing if the computer is turned off and then turned on.This is also a fresh unformated hardrive. This is my Mobo,video card and processor.
