I installed Windows 10 + all latest updates on my Mac Pro.
video card is Sapphire HD 7950 Mac Edition

I installed games via Steam Half-Life and other old games are ok but example if try start Half-Life 2 or other "not so old" games screen goes black and Mac restart. I can see ACPI error in windows log but nothing else.

I installed latest AMD drivers -< same issue still.

Any thoughts

Event 13: ACPI

: The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly.

Windows 8.1 seems to work ok
Also almost all games work under El Capitan. 👍
