Your laptop might be overheating. Can you check temperatures using tools like HWINFO? Here's the link to it: Free Download HWiNFO Sofware | Installer & Portable for Windows, DOS. I've provided the steps to check the temperatures:
Click on the Sensors-only checkbox and click on Start.
Monitor the CPU Package and GPU Temperature.
Check how hot they get when you're gaming and let me know.
