This looks to be in the category of being a desktop so my answer would be that the video card has gone bad. I would either take the computer to a qualified repair person or you can troubleshoot this yourself by buying a new video card and putting it into your computer and testing it.

If you are thinking of doing it yourself you should look at this tutorial http://www.heatonresearch.com/articles/25/page2.html

Make sure your have the plugs in the right place. There will be 2 coming from your monitor. One in ac wall outlet and one 15 pin male that goes into the back of your computer into the video. If your using the on board video or even a video card it may be that it's bad. Are you sure the monitor works.
If you have some spare memory sticks try changing the memory first. No video is usually first sign of bad memory. Video cards are second.
Cpu running is a good thing. Narrows down pretty much to memory, monitor or bad video card.

Has this been happening on a regular basis? When did this start? If you have a separate video card are you capable of disconnecting it from the motherboard and attaching the monitor to the built in video?

Also as strange as this seems, I have seen some instances of a blank screen where motherboard ram not seated properly can lead to a no post situation.

What would cause computer not to turn on when the power is loaded and the screen to stay black?


Im sorry about your situation.

Does the computer turn on??
If the computer turns on do you hear or can you see the fan working??

If the computer turns on does it stay on or does it shut down after a few minutes??

This will help us determine what is going on.

Blank screen when Gateway GM5664 turned on


How do you know your mouse and keyboard work if you have a blank screen?

What motherboard did you put in it? Did you install a video card or using a built in video card? How many beeps? Do you have a spare video card to put in the system and try that?

My computer comes on just fine, but then while loading the screen goes black. You can hear the computer still working. Sometimes the screen will pop back on but it will be faint and flicker then goes...


Regarding the blank screen, your monitor is most likely faulty - I'm assuming an LCD screen, in which case the backlight is failing, possibly the tubes or the the inverters.

Regarding the fans, you may have pulled the fan leads out of their connectors on the motherboard. Check to see if the CPU fan spins while the computer is switched on.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.
