My computer won't turn on. What do I do?

My first guess is a power supply problem. This is what your power cord plugs into on your computer. If you are short on time, take it into your nearest computer maintenance store. However, these places usually charge much more than should be charged. Try finding a flier around town of someone who says they fix or build computers. Students are always happy to fix a computer, and they will do it at a fraction of the cost.
