computer and screen not working together

[mannerda]

The computer is a gateway model#GT5232E, Windows XP media center addition. my computer was working and I had to shut it down to get our internet back up and running, and when I turned the computer back on, the monitor says it has no signal and the computer boots up like normal with the sounds.  I switched out monitors and cords with another computer, and it still does the same thing. both screens work with other computers.

How did you go about your internet connection with that particular PC? Did you made any hardware install such as a network card or recent setting changes? Have you tried reconnecting all external devices or internal components(RAM, Video/Sound card, Cord/Cable connection)?

my internet connection is through xplorer net, I called them and they where the ones who told me to turned it off, so they could ping it or something, and 2 minutes later they told me to turn it back on. the computer is all original we have switched out cords with ones we know that works.

Sounds like a problem with your video card. If you have a video card (not integrated into the motherboard) try taking it out and re-seating it. If you do have integrated video, try an add-on video card.

I just tried that and still nothing.

After doing some research on your computer here is the best guess I can give. You indicate that the gateway has not been modified and you did not make changes to the software. The computer stopped responding and you turned off the power.
Based on that information, a cable or connection came loose inside the PC.That is a wild guess, but it is all I could find that meets the information you gave. Another possibility is the Video card failed. Or the card came out of its socket. I assume that this model came with a video card that has a PCI or AGP socket and is not on-board video. There is, I think, a cable that goes to the video card.
The fact that you here the sound indicates that everything else is working.

But in any case I do not recommend buying a new video car. Not yet.  If you have a friend that collects old computer parts, ask him if he has an old video card. Try an old generic video card and see if it  turns on the monitor.

EDIT: Forgot to mention. Some video cards fail to activate the monitor, you can 'fool' the monitor by turning it off and back on again. I heave an old PC that does this and that is how I deal with it. I refuse to buy a new graphics card.

You've already tried another known good video card?

I think it is the video card I will try that, thank you all for helping me.
