How to find a car electrical short: Car stereo and power windows loose power simultaneously?

I have a 2000 Chevrolet Camero that has a short. The car stereo and power windows loose power frequently...maybe 10 times or more on a 30 minute drive. Is this something an unexperience person can resolve on their own? I'd like to try to fix it myself.How to find a car electrical short: Car stereo and power windows loose power simultaneously?
If you are patient and careful, You can shake wires and switches until one acts up. Then you know what to fix.
