MSI Vector 17 HX A14VGG Anyone help

Looking for anyone's advice or knowledge as my rig that I use for schooling, I have had an issue with the fans constantly running loud and it putting off a lot of heat, but it normally runs for the processes and tasks I need for school. But anytime I've tried to play any type of gaming on it, whether it be downloaded and played or streamed and played, my rig will crash within a few minutes of startup. It's only when it comes to gaming. Thank you in advance.
