Well, I just took everything out and rewired. I made sure no components were touching the case or any other metal parts (i.e. screws). Once all of that was done I tried booting it up again, and it worked fine. I think the problem lies within the power putton. Whenever I touch the bezel where the power button is, the computer starts, then immediately shuts off. If I directly press the button, it works fine. Any vibrations I make near the case will make it turn on (or shut off). Would i just need to replace the button or redo the wiring or something?
