I re-booted my computer the other day and now it will not display anything on the monitor. I have re-booted many times to the same result. I hooked the monitor up to another computer and it worked fine. I've TRIED to start the computer up in safe mode (using F8) and have yet to succeed at that either. What are my next steps to take? I'm at a loss. Thanks - PaxPax...

First thing to do would to make sure you have no loose CABLE connections.

Always check the cable connections with the computer powered off...and unplugged from any and all power sources.

Also make sure the monitor is off when performing these checks.same as before......If you are using a separate video card...Have you checked to see if the card is SEATED in its slot on the motherboard properly?

Also, is there more than one CONNECTION on your computer to hook up a monitor? Some motherboards and computer manufacturers have onboard video...check that, as well.

Also open BIOS to check your video settings...whether or not you have disabled onboard video.I get absolutely NO SCREEN image at all so I have no idea as to how to check my BIOS. It has a video card and was seated properlyIs there an onboard connection you can try?

Could be the hardware device is bad, or a Power Supply issue.
