Hello and welcome to Techspot.
First of all run a disk check and tick the box to fix errors.
Secondly right click my computer select properties and then the advanced tab.
Click on settings under startup and recovery and untick the box which says automatically restart,
Also set the write debugging information to none.
Now when your system crashes you should receive an error message which will tell you what caused the the problem.
If this doesn`t work then post back with the results of any error messages.

Ps please fill in your system specs including your OS in my.TS.forum at the top of the page(click on edit profile) Thanks.
