Galaxy S2 Turns on when battery is inserted, goes to boot screen then shuts off

[brokengalaxys2]

When I insert the battery into my Galaxy S2, it automatically turns itself on, the white SAMSUNG logo appears, then the boot screen. When it gets to the boot screen, it goes to a random amount of loading, stops, and shuts off. I can't turn it back on unless I take the battery out and put it back in. It was working perfectly fine a few hours ago and it suddenly shut off. There is no vibration during any of this.

Welcome.

A failing battery, perhaps?

Nope. Switched batteries to a different one and the same thing happens.
