issue with low res game coming out of sleep mode

Recently upgraded a friends computer to windows 10 and we're running into an annoying issue while playing a low resolution (800x600?) game. The game boots up fine and everything is great until we pause and come out of sleep mode when the whole image on the screen is compressed to half the screen with inverted colors (this same thing happens when the windows key is hit to go back to the desktop and try to go back to the game). The image isnt frozen, you can hear the sounds and see things lighting up. The actions are working on the whole screen but the image is compressed to the left half of the screen. So it seems to me that there's some software issue involving the graphics card since the computer is having issues switching between resolutions? Any help would be much appreciated, thanks

The computer is put into sleep mode with the game up?

Usually this does not end well for any game. older games will not alt-tab well either. (hitting the Win key to "tab" out is basically the same thing.)
Most likely the issue is the game losing exclusive mode and not getting it back.

What is the game you're playing?

The game is an older version of risk, would it help to uninstall and reinstall? We just upgraded to 10 (no clean install)
