What is wrong with my HTC One?

[AC Question]

My HTC One shuts on and off by itself and it only comes to the htc start up screen

Is this after a update?...clear system cache... Use Power and volume buttons... Look up how on Google or go to your carrier... They will help.

Welcome to Android Central! I agree--clearing the cache partition is a good start.
