Weird Gaming Problem. Any Thoughts??

Hey guys. Lately when I've been playing Starcraft ii, the game has begun to blink or flicker. It locks up for a second sometimes, and sometimes it also makes units/buildings all black without detail.

The resolution is 2048x1152, and I'm using a EVGA GTX 275 FTW edition. My settings are at Ultra in the game, and my card has never stuttered like this before when playing other games set at the Max settings.

Processor: i7 920
Ram: 6gb
Board: EVGA X58 SLI LE
HDD: 74gb WD Raptor

I've included a link to a youtube video of my screen while I mess around in SC. At around 30 seconds, the screen locks up, and then blacks out for a second. Sometimes when it returns to the normal play screen, the little monitor icon for input source DVI will pop up as though it was source checking or something. There are no instances of the blacked out units/buildings in this video, but several instances of the blinking/flickering screen, and the blacking out of the screen.

These are some of the more noticeable times in the video that you see the problem:


Has anyone seen this before, or know what it might be due to? I'm open to all thoughts. I'm just trying to figure out what on earth is going on. Let me know what you think might be up.

As always, thanks a bunch for all your help.

  1. this looks like your drivers breaking and recovering silently (meaning that it doesn't inform you with the usual tooltip from the taskbar

    have you tried reinstalling the drivers?

    also you didn't mention your power supply, but some cases like this are due to the gfx card failing from not getting enough power - resulting in the driver interruption

    Hello and welcome to the forums
    Like silver said,it could be a driver issue,so do a clean install of the latest VGA drivers,here is how
    1_Download and install "Driver sweeper" from and install
    2_Go to add/remove programs and uninstall the driver and reboot
    3_Boot to safe mode and open driver sweeper,then click on Nvidia and then click on clean
    4_Reboot and boot normally to windows and install the new drivers after that you need to restart,and its done

    My power supply is 600W. I'm not sure how to tell if that's the problem, although I had suspected that might be it for a while. Any way to tell?

    I tried your solution and it seems to have had some good results in a small test. I'll reply again if it comes back. Like silversurfer said, it could be the power supply.
  4. there kind of is a way without geting a volt meter and monitoring your actual psu usage - you can burn in both your cpu and graphics card at the same time and see if that disrupts the drivers for lack of power... im pretty sure thats what it might be
  5. so as it turns out, a number of people are having this problem as well. i've reposted the thread on the starcraft ii forums, and the conversation is continuing there in case you're interested. go there and voice out in case you're having the problem too.
