    Try taking down the screen resolution a notch. Sounds like the monitor
    can't take certain frequencies. By reducing your res, it MAY help. This
    could be a bad/borderline monitor issue. See if X is configured with the
    proper frequencies that the monitor can handle. Check the actual spec
    for the monitor, and fix the config file manually if necessary.

    Alternatively, on some MOBO's, the video is built in. The BIOS is
    usually set at some minimum RAM size for the video. I ALWAYS up that to
    32Meg. Even 64Meg if its available. If detection got the specs wrong it
    can lead to what she's seeing.

    Also, go thru the BIOS to make sure you have PLUG&PLAY set to yes since
    FC3 can make use of additional BIOS input as part of the install
    process. While in the BIOS, check all the settings for reasonableness,
    and turn off stuff she'll never use like serial ports, parallel ports,
    extra IDE channels, etc.
