    The computer I use can play TheSims2 on a CRT using an older Video Adapter, one that does not support Pixel Shader 2.0 or higher. But G.H.O.S.T. Chronicles after being played several minutes well into 2 hours sometimes causes my CRT to go dark. I have to reboot my system to get the resolution and brightness back. I think they said there was a bug in this game. A video game should not in my own personal opinion cause the monitor to go dark unless of course the monitor is getting old and just need to buy a new LCD or LED monitor that can handle the intense graphics of newer games like the above mentioned and also TheSims3 requires a new graphics card one that supports Pixel Shader 2.0 or greater and Norton keeps giving me which programs use the most resources that is at or above 100 percent. RAM is probably an issue in my case.

    Did you check your power settings?
    Control Panel -> Power Options


    Hello, if it is not a problem with you power saving settings it could be that you have the wrong refresh settings set on your monitor. Try playing with your refresh settings and if possible set it to native resolution.

    It could also be that you are trying to play your game with a resolution your monitor does not support. Remember that in your computer when talking about video cards there are two kind of resolutions, the one your graphics card support and the one your monitor supports. A possible solution for this would be to try and change the resolution settings to standard resolution your monitor supports. If you are not sure about what your monitor/gpu supports, just find the product manual and it should give you all the information you need. Hope it helps

    what game are you playing? How are you playing it, i.e. do you use the mouse, keyboard, a joystick, or something else?

    What is your operating system? Based on your hardware specs, I assume it’s Windows 7 64-bit.

    What do you have to do to bring the monitor back on? Do you hit a key on your keyboard, move the mouse, or do you have to hard reset / reboot the computer? In other words, does the monitor just turn off or does your computer freeze completely?

    My initial thought was that your monitor goes into idle mode and turns off to save energy. You might want to go through the power plan settings in Windows 7 or through the respective settings for your monitor.

    In Windows 7, go to Start and type > Power Options. Go to > Edit Plan Settings and check what > ‘Turn display off’ says. If it says 20 minutes you probably found your culprit. Set it to > Never.
