GPU keeps crashing

[Cam]

So I have the NVidia GeForce GTX 770, and my GPU kept crashing randomly. I then proceeded to update it, now it only seems to occur occasionally(every half hour or so) or when I do something that requires high GPU usage(H1Z1, OSRS crash my GPU but surprisingly CSGO doesn't)
Any help?

Try installing Msi afterburner and increasing the power limit to 115%.

You can try completely reinstalling your graphics drivers.

Also, make sure to monitor your Graphics card temperature while playing games that causes it to crash, if you notice temps above 90+ degrees Celsius then you might want to consider disassembling the GPU and replace the thermal pads and paste on the GPU Core.

Make sure to rid the Heat sink of any dust too. Check your fans are still spinning smoothly.

Also need some feedback as what you consider a "crash", what are the symptoms when your graphics card does this?

Take it out and clean it.
