I have occasionally experienced some Win10 freezes on my laptop when watching youtube videos (for instance like this one: https://www.youtube.com/watch?v=wijrestbx2U&t=2049s - a witcher 1 gameplay video). The laptop completely froze and had to power it down.
My laptop is an Asus TUF A15 with Ryzen 4800H and GeForce 1660Ti.
Any idea what could cause this?
