This seems like a unlikely issue, but I will do the best of my knowledge to help you, first things first I feel it has to do with the OS, and when did this start occuring? After any changes like anything installed, anything happen to computer? When it crashes is there any specific error or anything happen on the screen? More detail is needed like when you plug in the charger the computer just shuts off, or you get blue screen of death? Please provide me with everything that you experience when this crash occurs.
