Hello,
I've been having this problem for a while. The screen 'buzzes' randomly for a long amount of time. Everything on the screen including texts becomes blurry and sort of fuzzy. Usually it goes away for a week or so but then it comes back.
I don't remember exactly what did I do to make this problem occur.
I've already reinstalled BIOS, graphic driver, checked for updates. I've also connected my laptop to an external monitor, and the problem seems to not duplicate on the monitor, only on the laptop screen.
I cannot upload any videos to show my problem as I don't have the permission to do so, although I hope I can post it to explain my problems further.
Thank you.
