Horizontal Frequency Out of Range

Question

I've been running Ubuntu on one of my servers for about six months. Recently, every time I turn on the computer it POSTs and then right before it gets into Ubuntu my monitor gives me an error saying:

Out of Range
H: 92 kHz
V: 58 kHz
Range:
H: 22-82 kHz
V: 56-76 Hz
Max: 1280 x 1024

Obviously the horizontal frequency is at 92 kHz, which is apparently out of its range. It's an older (~2005) LiquidVideo 17" flat screen monitor with the old blue VGA input. I have access to the BIOS but that doesn't really help. If I had another monitor I would hook it up to that to troubleshoot and figure out whether it's the monitor or the graphics card or what. Even if I am able to get into the desktop I don't think there's a setting for horizontal frequency, only vertical. How do I fix this?

Here's a picture:

Try to attach better monitor, maybe that alone will solve the problem. Otherwise you can boot with bootable CD that work and edit Xorg.conf file.
