Question : Problem: Out of Frequency

PC with S3 OnBoard video card, LG monitor, Win98SE.
On startup it shows:

Out of Frequency
HF 27.8 kHz
VF 62.0 Hz
Operating Frequency
HF 30-71 kHz
VF 50-160 Hz

Changing monitor to another LG didn't change anything, but using one older ADI monitor worked, initially.
So, I installed some printer driver, changed BIOS (USB was not enabled) and after few restarts I'm getting "Out of Frequency" again. This time second monitor doesn't show anything.

Any suggestion?

Answer : Problem: Out of Frequency

I would say you have the wrong video driver for it, or the resolution is configured for values your monitor can't display.  Can you bring it up in safe mode?  I would remove the video driver and use standard VGA, then try to install the correct motherboard video driver (it usually comes with the motherboard).

By the way, what does a printer driver have to do with your video display?
