Have you tried updating your driver?
Post make and model and we'll help you find an update

If it is or your using an app to 'tweak it' please return to default values or stop using any apps involved.

Have you checked your gpu temperature when it has the issue?

What is the make and model of your computer? Video card? Video driver version? Power Supply?
