Question Flashing Red Blue dots on screen while gaming - video link attached (RTX2060)

Dec 14, 2021
My Laptop Specs -
Lenovo Legion Y545
NVIDIA RTX 2060 6GB DDR6 dedicated
i7-9th gen (i7-9750h)
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.

If anyone knows what exactly is the problem, please help me out in this.
Thank you !
