Turns out its the Nvidia latest driver on 14.03.2023. I reverted to the older one and its working fine now
Hi mates, I'm using m16 R1, i9-13900HX + RTX 4080 + 32GB ram. Browser is Chrome During normal use ( like watching YouTube, Facebook, Google Chat etc ), I face this issue: - First the machine stops working ( extremely lag, mouse moves super slow )- then it stops at all- then external monitor goes black for a few second, after that everything is back to normal- it just happened while I'm writing this post The interesting part is, it does not happen during heavy use like gaming. My game session normally can be 3-4 hours. What I have tried:  - use SupportAssist to reset to Factory- reset Bios to both Bios default / Factory default- uninstall / reinstall GeForce Experience and graphic driver Nothing worked. Please find attachment for Reliability Report. It shows lot of hardware Error [IMAGE]
