iPhone reboots every 5 seconds, isn't recognized by iTunes

I was using my iPhone and I saw the battery percentage drop significantly (it went from 60% down to 29% in an instant) and then it started rebooting on its own every 3 minutes while showing distorted colors of what was being displayed before shutting off (like pink tinted rectangles even spread throughout the screen). Now it can only show the apple logo and reboots every 3-5 seconds. I replaced the screen and battery back in January of this year (2014), there is also no sand or water damage if that is relevant.
