How do I get remote monitor to display?

There is probably something else than the monitor not working. If you can, open up the PC, and remove everything exeternal from the mainboard, then check if it works. do the drives power up? Do the Fans run? Try it with another powersupply, reseat the RAM, remove the CPU Heatsink, clean the surface of both, the CPU and the heatsink, then apply just an idea of thermal transfer paste, and put the heatsink back on firmly. If possible, try using another video card (if the board has slots where you can attach one).

I should have said that the system boots from a floppy and exhibits all of the normal activities of a diskette boot except for nothing on the screen.

Then probably the video card isn't working, and as this is probably integrated on the mainboard, try inserting a video card.

Also check with gateway for warranty repairs.

Okay, Let's rehash the facts. I have checked with Gateway and the machine is out of warranty.
This is an "all in one" machine with everything integrated into the display housing.
There are no card slots of any kind!

The monitor is dark.
There is an external monitor jack but when I plug a working monitor into this it does not display anything either. This would imply that the video driver is at fault, but it is integrated into the mainboard.
WHen I start the machine, it appears to go through POST and and then there is access to the hard drive. But nothing on the screen.
I need some suggestions on how to troubleshoot this or should the whole thing just go into the garbage?

I would like to close this question but feel that the responses were of no help at all. I already knew or tried everything that was suggested.
