I am a user of Acer Swift 3 (Model: SF314-51). I had just updated my BIOS from v1.07 to v1.10 yesterday. I can 100% confirm that I downloaded the official and correct BIOS setup file from Acer website and the update completed successfully without any error. Since then, whenever i try to play videos online using [Fullscreen] mode, my computer will completely auto-shut down after few minutes. I have tried on Google Chrome, Microsoft Edge, both are having the same problem. I tried to downgrade my BIOS back to v1.07 but the v1.07 setup file said that I can't downgrade the BIOS. Any solution, guys? I hope that Acer can immediately release a new BIOS update patch to fix this CRITICAL bug. For me, personally, I think this issue is related to either BIOS, GPU, or Flash Player. But I am sure that my Intel HD Graphics 620 driver is at the latest version (220.127.116.1101) and my Adobe Flash Player is at (18.104.22.168), which is the latest as well. All my drivers are up-to-date, I checked them using Driver Booster 5 Pro and my Windows version is also the latest (Version 1709 Build 16299.192). I tried to play my offline videos via VLC player using [Fullscreen] mode, it works just fine without causing my laptop to shut down. This issue only happens when I play online videos including those from YouTube.
