I must say you are quite bright for your age Robert.
If you are recieving no power, I would suggest the culprit would be one of two things. The motherboard may be touching some part of the case and grounding itself out, or the PSU has fried.
Open up the case and smell around for any burnt smells or anything of that sort. Check all power connections and make sure that the PSU is hooked up and working properly. Also make sure the switch at the rear is set to the appropriate one position.
If the above fails to solve the problem, begin slowly taking out unneccessary parts one at a time and see if anything turns on. Hopefully that can get it to a point where even if there is a problem, it should report a beep error via the POST and you can pinpoint the problem.
