What's going on with my computer and monitor?

I've been experiencing a weird hardware issue of late. I have AMD 350, Red Fox Ali Motherboard computer with and All wonder PCI video card. Everything was fine but lately the damn computer will not work with my monitor. I tried the computer on a Gateway Trinitron monitor and it worked but when I attach it to my KDS monitor no there is no comunication between the PC and the monitor. The KDS monitor works fine because I've attached it to 3 other computers and have not had a problem. I think the problem might be with the power supply in that it may not be able to produce enough power to power up the monitor. I don't know.....If anyone has any ideas or suggestions or even explanations please let me know.

The monitor wont turn on at all?
It should have nothing to do with the P/S of your computer...The monitor has its own AC.
What monitor profile are you using? Hook that trinitron back up, and go to display properties. Go to advanced, and check the monitor driver......If there isnt a KDS profile that fits your model, then use the generic plugNplay profile....

Make sure the resolution and refresh rate that your video card is set to don't exceed what the monitor can handle. (This usually won't give you a completely blank screen, but it can, depending on the monitor.)

The monitor has power but there is no sync.....the LED next to the power switch just blinks orange instead of being a solid green....now this monitor used to work well with the computer it just doesn't want to work lately.....

I'll check to see if the video settings are set correctly but I don't think that's the problem....I tried using another video card and I got the same issue.

As for the KDS profile it should be in the computer because it did work at one time.

Anymore suggestions are greatly appreciated.
