Ok, so I can start and play in single/multiplayer games just fine...However when I play Demigod after about 7 minutes of actual gameplay (Once the game has started and I'm playing) my monitor will just go into sleep/turn off and the light will go from green to yellow rendering me unable to see anything. I cannot tab out of the game, I cannot Alt F4 or CTRL + ALT + DEL or anything.
Basically I have to reboot, and Demigod is currently unplayable for me. This has NEVER happened before with a slew of other games I play regularly...
I have a Radeon XT1900 video card. I'm currently running Windows 64 bit.
Any help would be greatly appreciated. Thanks in advance.
