I'm pretty sure the issue isn't "monitor" related as a monitor wouldn't cause games to crash and force a PC restart. Sounds like the PC is over heating or there's an issue with the GPU itself.
Of course it's all guesswork without proper system specs. It would also help if the OP gave us an example of a game(s) they're having issues with.
And yes, it might be worthwhile to uninstall Afterburner to see if the issue persists.
