htc desire z keeps restarting on its own My HTC Desire Z keeps restarting on its own continuously, how do I stop it and how can I switch on my phone now? I tried removing the battery but that didn't work. 

Can anyone help?
Pull the battery, put it back in press volume down +power , it will boot into Hboot, then use volume to scroll down and select recovery, then restore a backup or flash rom again.
