Nokia lumia 720 black screen

[studenttech]

The nokia lumia 720 has been having a really annoying problem,it happens like once a month where the phone turns itself off and needs a hard reset to be switched on, doing soft reset wont help only shows the nokia logo and then again switched off. I'm tired of doing a hard reset every month, and restoring my data over and over again. Any solutions?

Can it be taken in for service perhaps? If its under warranty I'd call up support.
