Monitor goes black when playing games

By jeffro1220

  1. Sometimes when I am playing a game such as WoW or Team Fortress 2, my monitor goes blank and on a few occasions has been slightly different colors. Everything but the monitor appears to contiue running, but nothing responds. The only other noticeable thing when this happens is that the harddrive starts to make a noise similar to when it boots along with a flashing red light on the front of the tower. If I let the computer sit for a minute or two after it goes blank, it makes the "beep" sound when it boots...except it doesn't reboot, so I have to press the restart button to get it running again.

    This has never happened while surfing the net, writing documents, etc, ONLY when playing a game. It does not happen extremely often, maybe 1-2 times per hour.

    e-GeForce 8600 GT video card
    ASUS P5N-MX motherboard
    Intel Core 2 Duo E4600 @ 2.40GHz
    2400MHz Core speed
    DDR2 2048 MBytes
    PCI-Express x16

    Help would be greatly appreciated!

    Hi Jeff,
    That 'beep' that you get is probably telling you that your computer is not meeting all the hardware requirements for the P.O.S.T. (power on self test) but it sounds like your video card stops responding to commands from the display driver. whats happening when this goes on? like gpu temp, is your card overclocked? certianly not the only things to cause this but among the most common.

    How can I check if my card is overclocked?

    if you didnt OC it, its probably not. monitor your gpu temps to make sure its not locking up due to overheating. Are you getting any error messages when this happens? you might try downloading the latest drivers for your graphic card as well if you have not done so. let me know how that goes, if it continues we can take the next step.

    Looks like you might not have enough power coming from the power supply to run your computer properly. Either that, or something (likely the video card) is overheating.

    Just downloaded the newest drivers and the problem still consists. There are no error messages when this happens either, screen just goes blank.

    That was my first guess when this started happening, so I'm going to look into getting a new PSU. I'm using a 600w right now.

    The monitor is a brand new ViewSonic 19" widescreen HD. I just got it for Christmas.

    One other note: I just moved some items onto the same table as the tower, one of which was heavy enough to "shake" the table just a little. This caused the problem to happen. I rebooted and went into the game again and lightly shook the tower which again yiedled the same result. Odd thing is that in the past when I was first noticing the issue, there was no movement nearby or anything that would cause the tower to move.

    Hi Again Jeff,
    Did you get a chance to check out the gpu temps? you can download this program if you dont have one, and let it run and log your temps while you play. overheating is rather common symptom of this. and 600w psu is enough juice for your rig (if the psu is stable)

    Maybe the video card is loose in its socket... that might explain the crashes when you shake the tower at all. Try reseating the video card, make sure it goes all the way in and is tightly bolted down.

    Monitor goes black when playing DVD's if computer is moved

    I have a similar issue as Jeff and am wondering if it could have a similar core problem...
    My IBM thinkpad is about 4 years old and in the past month when I've played DVD's on it, if the PC is moved AT ALL the screen goes black, the DVD stops playing, but the green lights just below the monitor are mostly still all on. I also have to reboot it myself and then it works fine. I have sat perfectly still and gotten all the way through a movie so it does work and its done this with more than one DVD. What might make it do that with the slightest move? Could it also be the video card???

    Video card

    Okay, so it appears that I don't have a video card on my laptop after all...what then might be causing a blank screen during movies after the PC has been moved even an inch....?

    Well, iv heard that the problem might be in the graphics card or over heating or both... im not sure so dont take any actions. If you could, double check. But from another forum the changing of the graphics card solved to problem with WoW. Well if you wanna be safe try plugging in another monitor just to see if the problem persists because the monitor might not support the game as in FPS or resolution
