OK, so I have a thread in Build Your Own PC, but considering this is a hardware issue, I'd like to move it here. My computer was running fine, I moved some components around and now the computer cycles through it first boot stages, turns off, turns back on and goes to boot. It reaches the Asus ROG logo "red glasses" and shuts off totally. I have no idea what is causing this or how to fix it. Any ideas? E2A: Fixed. Loose fan.
