Razer Blade 15 Advanced 2018 crashing/freezing

I recently purchased a used Razer Bade 15 Advanced and am experiencing several problems.. Launching a game will cause the machine to freeze/lock up and only a a power cycle will get it work again. Ive checked that the video drivers are up to date: they are. Im new to PC gaming. I have also gotten a few blue screens twice was the WHEA error once it was a clock watchdog time out once it was irql not less or equal I understand that there was a possibility that I would have some bugs to work out, and like I said I am new to pc gaming trouble shooting, so.... help...
