See if you can boot the device into safe mode. Remove the battery. While holding down the back key reinsert the battery. Continue to hold the back key for another 20 seconds. The device will then boot into safe mode. If it boots up then you'll want to delete all third party apps or whatever you might have installed that caused the problem. If it doesn't boot up then here is KB that gives instructions on what to do:
