Hi, Have you got a video card plugged into the motherboard or is it using onboard video? If it is a card, have you tried re-seating it (removing/reinserting it, with the power off, of course) and then trying it? Has the motherboard got onboard video that you could try, in case the plug-in video card is faulty. If so, with the power off, remove the plugin video card and connect a monitor into the onboard video output. Can you boot successfully to the desktop when connected to the onboard video (if available)? All the above is trying to prove is whether the video card (if installed) is still OK and if not that the PC still works with the onboard video (if applicable) connected.
