before i get bombarded with requests to put this on a different forum...let me just say i dont think this is a monitor issue. one of my PC's just plain stopped working the system powers up but doesn't display on the monitor, however the monitor works on a different system.

If anyone has any ideas as to why this happens i would be greatful
 
If nothing displays on the monitor from a cold shut down - no BIOS data, no system data, nothing - then I would guess it is a video card issue. It is possible that something in the card failed (or if integrated video then something on the board failed) but the rest of the card is still working.

One way to test is to take the video card out of the system that you tested the monitor on. IF it at least gets to the BIOS data screen, you can abort the startup. Then you will know that it is a video card issue. To further eliminate any issues, plug your "bad" video card into the good working system and see if it will show bootup data.
 
A blank screen from a cold-start is usually a sign that the system is failing POST prior to the point where video is enabled.

If you can try attrofy's suggestion, then by all means do that as it will eliminate the video card as the culprit. The usual course of action in these cases is to strip down the motherboard to only the essentials: memory, CPU, video card, keyboard. If POST runs, then add things back one by one. This idea and others are covered in faq602-2731
 
additionally, if you have a PS/2 keyboard cycle your num-lock caps-lock key and see if the corrisponding LED cycles as well.

This generally tells you if your system is really running - even if it doesn't look like it. If the LEDs cycle, your system is really running and the problem is probably not so serious (like a bad video card). If they don't cycle, your system is hung and the problem is from a more essential component like your CPU, Memory, PSU, or Mobo.
