    Problem:"Monitor Frequency out of range"

    I installed Fedora Core6 on my computer. When I try start Fedora Core6, I get the following error message:"Monitor Frequency out of range". The system hangs-up with this error message. How do I fix this problem? And how can I enter the command line?

    My computer:
    CPU: AMD Sempron 2500+
    video card: ATI radeon x700 se
    monitor: ViewSonic va721

    In the grub loader menu, press e on fedora ...edit second line and append 3 in the end... it should look something like this
    /vmlinuz-2.6.18-1.2849.fc6 ro root=LABEL=/ rhgb quiet
    this will make u boot from $ prompt.

    login as root and type
    here u can change the screen resolution.. change it to 1024x768..

    as suggested by karthikmurs, boot up in command line mode, log in as root. execute this
    configure display settings, resoultion etc. type 'startx' after correcting display settings.
    in case, it doesn't work, execute this
    less /etc/X11/xorg.conf
    post the Section "Monitor" here.

    It is amazing what you can accomplish if you do not care who gets the credit.
