So this morning I started playing Witcher 3 and after 5 minutes, maybe less my system Reboots. I played for at least 4 hours yesterday. It has been good for months. I looked up Windows Event Viewer and got this message...

It happened a month ago with the Sims4, but i just re-installed it, and it works again, i tried that with the witcher, but still reboots. Sorry for the long message, and not sure this is the correct forum.

Not sure what i should do next, i tried googleing the question, but i have tried all of the common issues, not sure if anyone has heard of a Kernel Reboot Issue.
Thank you.

Please do try doing a clean install that I also suggested to others that had the same concern with their PC.
- Go to Device Manager and uninstall the Nvidia graphics driver.
- Next is to open Programs and Features then uninstall anything related to Nvidia.
- Once done, download and install the latest driver.
- Here's the link:
- Reboot the laptop once the latest driver has been installed.
- After the reboot, do set Nvidia as the default GPU.
- Here's how:

Just as an addition to Laptop_Nerd, I also updated my BIOS and re-installed all Nvidia drivers and Knock on wood, my system has been flawless, I didn't think the updating BIOS with kernel issues, related to my issue but it worked, I tried the Nvidia thing which allowed me to play 30 minutes before reboot but Flashing the BIOS now let's me play for hours. Thank you laptop :)
