There are many reasons why your computer can be crashing but let me help you know what it is.
I first would like to know more about your system. Please provide the following:

- 2.Attach the graphics report here.
How to get it?
Dxdiag Report: Type dxdiag in Start Menu> open> Save> Copy/Paste here.
Graphics Report: Right click on desktop> Graphics Properties> Options> Drop Down Menu> Information Center> Save> Open .txt file created> Copy/Paste here.
Besides this, can you please update the BIOS in your system?
