If nothing at all ever shows up on your monitor your system may not be completing post. Consult your motherboard's manual. All motherboards will give you some indication of post results whether just a series of beeps or something more advanced.

If the post code indicates a successful post, then make sure your monitor is connected correctly. If you are using a video card in a PCIe slot make sure your monitor is connected to it and not to an onboard connector.
