Default [Q] Phone shuts down immediatly after screen lights up

I'm not sure what has happened here. I pulled the phone out of my pocket, and it was frozen. So I held the power button for 10s and it turned off. Since then, it won't turn back on. Usually it lights up for about a second on the "Quietly Brilliant" screen then shuts back off. It has gotten stuck on that screen, with the phone vibrating a few times. And if I hold the volume down and power button, it will show the boot loader screen for a second before shutting down again. I have no idea what happened here... It's really annoying. I've had so many issues with my EVO LTE in the past few months, it's ridiculous. I own two, and the other one is currently on it's way back from HTC after it's second warranty repair in as many months. This one is rooted running MeanBean. S-On if I remember right.
