Carson Mould, check your power cable first. Make sure it is properly inserted and that you have power on the electrical outlet where it plugs into. If that works, you do want to take a multimeter and check the power switch and see if that works. Remove all the RAM and unplug every device that is connected to your computer. Then try it. If it still does not work, your power switch is okay,, and the power cable okay, I would start off with checking the power supply. This of course will depend on your skills and tools available, let us know what you can do. Hope this helps, good luck.
