Okay, another thought is that you're using a video card which requires power from PCIe power connector(s) or your typical 4 pin molex connector. If it is not receiving that signal, it will not display anything on your monitor. The other thought might be that the system is not recognizing the video card and is still using onboard video. See if there's another port for your monitor, then try using it instead. If the screen comes online, we know the system is still using onboard video as opposed to a video card.

Let me know what you found. I'll be able to come up with some more ideas once we find out if you've got onboard video or a video card and if that video card requires its own power source.
Hi. On some motherboards the 'Enable usb Support' option in system can cause this. Use a conventional ps2 mouse and keyboard, unplug all usb devices, enter system and ensure that 'Enable USB Keyboard Support' is turned off and continue setting up as usual. Try locating a bios upgrade for the mobo concerned.
