    Text flickers below the icons on my desktop
    « on: May 30, 2011, 04:14:46 PM »
    I have been experiencing some flashing text under my icons on the desktop and the edges of open windows jiggle a little too.

    I have updated my drivers and the problem persists. Is this a bad video card?  Resolution 1280X1024 at 60Hz.

    The flickering comes and goes but is mostly in bad condition.

    I knd of reminds me of a flourescent lamp flicker but does not have an overall affect on the rest of the monitor so I don't think it is the display lamps.


    It looks like a ripple through some of the open windows, especially if they are light colored.
    All Help will be appreciated.

    Well the 2 possibilities are the monitor...or the card itself...
    Try another monitor to rule that out.

    How does it look in safe mode?

    LCD displays have fluorescent lamps.
    As LCD panels produce no light of their own, they require an external lighting mechanism to be easily visible. On most displays, this consists of a cold cathode fluorescent lamp that is situated behind the LCD panel.

      It works fine as long as I am in safe mode. I uninstalled the current driver and uninstalled the card in device manager then restarted and re installed an older version of the driver.

      Funny thing is that this just started after I applied the newest driver. Before that it was working fine. Almost like the driver destroyed the card. Could that be true?

      could  be the clock/sync on the monitor itself. Also, is it at it's native resolution?

        It is at its native resolution and it never flickered at all in safe mode.

        safe mode uses a different resolution and as a result different clock/sync settings. These would be adjusted on the monitor, and they cause the exact symptoms as you've described them- it could also be degradation of the cable if you are using a VGA connection.

        Also, in safe mode only Windows generic video driver is loaded.

          It looks like this may have been some kind of interference from a Blu Ray drive which was failing. As soon as the drive was removed everything went back to normal.
