My Laptop Specs -
Lenovo Legion Y545
NVIDIA RTX 2060 6GB DDR6 dedicated
i7-9th gen (i7-9750h)
16GB RAM
144Hz Display

Issue with the Laptop -
Whenever I play any High Graphics Game, red and blue dots start flashing on the screen immidiately. After running the game for about 10 min, the game crashes.
I have recorded some clips while gaming and have uploaded it on the drive, here is the link to it. I have played Forza Horizon 5 on very low graphics and also on high graphics. Both videos are there on the drive.

Thank you !
