Was playing xenoverse 2 on my Lenovo z50-75. It was on on charge and I unplugged it. Then there is a red screen and laptop restarts. I have run bluescreen view & whocrashed. Results say Thread stuck in driver -atikmdag.sys and thread stuck in driver m - dxgkrnl.sys Tried using DDU to completley uninstall AMD graphic driver n reinstall no luck. Updated BIOS still no luck. This happens whilst gaming n unplugging charger only.
