freezing/bricking issues

[Guest shaunt]

Yesterday, my Blackjack began to randomly shutoff and freeze (often while not in use). Later in the day, when turning on my phone, the screen began to look really convoluded and weird (as if the home screen were made of clay and someone had mixed it around). Now, my phone won't turn on at all. Anyone have any ideas what the issue is on my phone? Any troubleshooting tips?
