|"yes I have a good power surge protector, and the light is still green..."|
Some anti-surge devices have two or three led's - are you sure you are looking at the one that indicates protection is still there? Is everything protected - your router if it has a wired network connection to your computer, your telephone line if it is connected to the computer, your printer, etc.?
It is much more common for a bad PS to be the cause of no boot than anything else.
It is quite common for a damaged power supply to partially work, yet not be capable of fully booting the computer - and some outputs on ATX power supplies are on all the time the computer is plugged in and powered. If you can try another used power supply of sufficient capacity, try that - just make sure the wiring colors and number of wires are the same for the main connector.
That is the easiest thing to try. Any other cause would require swapping known good components into your mboard, or trying your components in another compatible mboard.
The svideo jack on most video cards is for TV out - you would normally connect it to a TV, not a monitor, and that feature would probably also have to be turned on in the Display properties in Windows - but that's of no help if the computer won't boot.
"I suppose it could be the video card, but if it could not detect a video card, the system would beep .."
Normally the mboard will beep if there is no video card, or, sometimes, if it is not inserted in it's slot correctly, but I've seen cases where a damaged video card did not cause the mboard to beep (the video cards were damaged by a defective power supply that put out too much voltage, or that had shorted out).
