Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Sorry to hear about your phone. First of all I suggest that you try to start your phone without SIM and SD card inserted. If the behavior still persists, I would suggest that you try to repair the phone software using PC Companion: 

http://www.sonymobile.com/update

In PC Companion, press start on Support Zone > Start on Update the phone/tablet software > click on the blue highlight (Repair my phone/tablet). Do this without the phone connected. Follow the instructions on screen to perform the repair.
