You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.
Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).
Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

My Xperia Z is currently doing this exact same thing. It won't stop rebooting. I've tried to turn in off dozens of times and it won't stay off! I did the power button/up button/vibrate three times thing but it just turns itself back on and keeps trying to reboot. With the same error message. This happens on both the wall charger and the computer. The computer won't even recognize that my phone is plugged in so I can't use PC Companion like I normally would. If I unplug the phone entirely and turn it off it will stay off but that doesn't solve the problem at all.
