System gets restarted and graphic driver gets crashed

My cesium application with 3d models runs perfectly on the following system.

I have following applications: google chrome, wampserver
I have following system specs: windows7, builtin graphic card, 8gb ram

The problem occurs at once :

Suddenly while running app, system gets restarted with no bug showing.

And now whenever I run my app, system will restarted again and again. (It happens while loading 3d models)

And then wampserver is crashed, graphic driver is crashed.

I have to remove and re-install every driver to again run my application.

It will run perfect again.

And same process will repeat.

Please help me out

Can you reproduce the problem with a simple Sandcastle example?

What version of Chrome?
What graphics card?

What version of video card driver?
