What you posted seems a little extreme for the beginning, but there are plenty of how-to’s that teach you the basics from the beginning, honestly just the first set of videos from an A+ video. Won’t turn on? First thing you do is unplug everything, give it a couple minutes, try it again. Still won’t? Same thing, but hold down the power button while off and unplugged (so it discharges the capacitors), then try again. Still no? remove cmos battery and do the above…I’m not sure exactly what videos you’re looking for, but there are definitely lots of them out there. Sometimes it’s a matter of asking the right question.

You should do away with it altogether and get an inline heater. They’re magical! Hot water for hours. I’ll never go back.
