Emachines power supplies have been going out and taking out mobos with them. We've seen a LOT of this.
You can check to make sure everything is well seated (cards, RAM, etc) and check the mobo to be sure all the capacitors are still good (not domed, rusty, or oozy, but nice and flat) and if everything checks out, it's probably the psu/mobo issue.
