Phone won't boot past Bootloader

[phstratton]

Specs of the phone I'm working with:
Make: HTC
Model: EVO Shift 4G
Carrier: Sprint
Radio: 1.08.01.0111

Currently completely stock, no rooting. The phone shut itself off when I was on Facebook. I pulled then reinserted the battery and it came up to the bootloader screen when I pressed the power button. The volume down and up button both appear to be working normally. I've tried booting into Recovery and it goes to a white screen with 3 android guys then goes back to the bootloader where my options are:
-Bootloader
-Reboot
-Reboot Bootloader
-Power Down
Upon pressing Bootloader I get:
-Fastboot
-Recovery
-Factory Reset
-Simlock
-Image CRC

When I press Reboot, the screen goes black, and nothing happens until the battery is pulled, then it goes right back to the bootloader. I tried factory reset, and again it goes to the white screen with the 3 android guys then back to the bootloader screen. What do I need to do? Thanks!
