Rich, was I ever glad to find you! I'm having exactly the same problem with exactly the same machine. However, I'm NOT a particularly good geek, but I'm daring. How hard is it to learn to change the power supply? And did you encounter any problems with getting shocked? :>}

Thank you!

Power supplies are easy to replace; it's usually just a question of fiddling with a few screws and connectors, as the power supplies themselves are self-contained boxes which just slide into the inside of the machine.

A search for the keywords [search]emachines "emonster 500" "power supply"[/search] should help you find the right supply.

I agree this is a very easy process. I wouldn't be afraid of getting a shock because you are not opening the power supply, so there really isn't anything to touch. You can go to Best Buy or Circuit and pick up a power supply, just get same or better than what you have. If unsure take old one with you.
