Without any visual or audio feedback, its tough to troubleshoot. You may need to visit your local computer repair store for assistance, unless you have access to additional parts that you can use to start switching out components to determine if there is a component failure such as the power supply or RAM, or if you have a short on the motherboard.

To troubleshoot this, you unplug everythign except the bare minimum (power supply, video, and min ram needed by the motherboard. hard drive, floppy, audio, USB components, should be unplugged. Boot and see.. swap out the parts until you find the problem.
