error and windows restarts

Whenever I launch unreal engine .I get this error atikmdag.sys

Quick google search suggests it is related to old ATI Radon cards.
Try reinstalling any ATI/AMD drivers you have on your system.

thanks…It was with my laptop power supply…it was plugged in but not charging thats the reason my grahics card couldnt work properly and causes this error

Thank you for the update!
Hopefully it will help someone in future :slight_smile:
