Why does my tablet keep shutting itself off?
My Nexus 7 has been having a problem the past couple of days where after I turn it on, it will run for a few minutes, and then it will freeze and the screen will go black, showing up with the google reboot screen a few seconds later. If I leave it completely alone, it will stay on for about 6 minutes before it shuts down completely, and if I try to actually do anything on it it turns off in way, way less time. I haven't been able to pin point it to a certain app of process, though some things will shut it down faster than others. It is making it impossible to use my tablet and I don't know what could be causing it.
