The first step in power supply diagnostics is determining whether or not the power comes on. Can you hear fans turning and drives motors spinning up, see little lights on the front of the CPU case or hear any beeps? If the system case is hot (if you get a shock) pull the plug immediately - you have a ground failure and a short. Once you are sure it's a bad power supply and not just a loose connection or something, then replacing it is easy.

You probably have the standard ATX PSU. Figure out what wattage you need and check out newegg.com for some great prices. Not knowing your system, I'd say to at least go for a 300W or 350W...but this does depend on your system also.

I'd check connections and look for shorts first, then replace the PSU if you cannot get it to work.
