My Aspire E 15 for some time now for no reason every few hours just shuts off

[catmandocando]

My Aspire E 15 for some time now for no reason every few hours, just shutting off, the screen goes black without any warning, then the 'ACER' sign appears. I must then restart it this is very annoying. It then comes up with the page did not shut down properly, restore page. It is fully charged as it is connected to the power supply.
Is there an easy remedy to correct this or must it be returned to the store where it was purchased? Thanks.

If it is new and doing this, take it back.
