Problem:
This "Signal frequency is out of range" problem is cause of incompatible monitor
plugged in your computer. If you replace the monitor, this error will display. I
encouter these problem mostly when I replace LCD monitor and not easily recog-
nized by the computer.

Solution:
1. Uninstall the VGA driver through device manager. Right click My Computer
    from the Desktop and choose Properties.

2. System Properties will pop up. Click Hardware tab and click
    Device Manager button.

2.Device Manager will pop up. Locate Display adapter. Right click on it.
   Choose Uninstall.

4.Uninstall dialog box will pop and  choose to uninstall the driver.
5. After you uninstall the VGA driver, install it again.
6. You can download the VGA driver of your motherboard on the
    internet. If you have the CD of your motherboard driver, insert it
    on CDROM drive and install it.

This procedure will solve the Signal frequency problem of your computer.
