Windows 8 Laptop Turning Itself Off?

I am currently running with a HP 15.6" Envy Laptop PC, Midnight Black, dv6-7229wm - Walmart.com I have not had problems before. While I was playing Diablo 3, on medium settings, the thing just cut out. The first time, i didn't think anything about it. I turned it back on, and it turned off again twice during the HP boot logo. So i took out the battery, waited a little and started playing Diablo 3 again, and in about half an hour it turns itself off again. Each time it turns off, there is the pop of the audio going out. So, i turned MSI after burner on (I have not over clocked this system, I just have MSI to watch the heat when I was messing around one day)

Anyway, here are the last three temperature logs from MSI afterburner before it turned itself off.

Code:
02, 24-05-2013 15:09:13, GPU1 temperature ,GPU2 temperature ,GPU3 temperature ,GPU1 usage ,GPU2 usage ,GPU3 usage ,GPU1 core clock ,GPU2 core clock ,GPU3 core clock ,GPU1 memory clock ,GPU2 memory clock ,GPU3 memory clock ,GPU1 memory usage ,GPU2 memory usage ,GPU3 memory usage 80,

[Code] .....

The log isn't coming out how I wanted to, but it was about 95-99 for all of it. I am playing on a table (As level as a table can be on a 40 year old brick floor), with nothing anywhere near the laptop.
