Video Problems

some older monitors and cards have a problem with high resolutions AND high color. the answer is either to slow down the color 256/15bit/16bit/24bit/truecolor
try dropping down the color one notch,
and or sometimes ive found that going to 1024x768on smaller monitors, even though hard to see doesnt do the run across the screen. dont forget your f4/f5 to go into safe mode if you get a screen you cant read/see.

First, you may not have enough video memory to support the mode (4 meg minimum)
Or, your video card may not set the correct refresh rate for your monitor.

Second, Windows Update is not the best source of device drivers for Windows 98. (even for XP, Microsoft is several months behind, and does not have a complete catalog.)

Identify the:
Motherboard / chipset
Video card
Monitor.

Resources to aid in the search for the correct drivers:
www.motherboards.org
www.wimsbios.com
www.driverguide.com

Install drivers in this order:
Motherboard / chipset
DirectX (Microsoft)
Video card
Monitor.

Go to your monitors web site and download the driver for your monitor. Update the driver in device manager and that should help limit what the options are in display so that you don't exceed what the monitor is capable of.
Do the same for the video if necessary.
Good luck.

I believe it is the monitor itself. I just found out it is a 7 years old monitor at a minimiun. I believe it is time for a new one I don't think drivers will help at this point.
Thanks

Do you have Norton Utilities installed on this
PC. There is a monitoring program that loads by
default that caused me 2 weeks of research to
realize that it was causing a problem similar to
yours. I disabled it and the problem ceased.
If you can boot in Safemode, and it does not
happen than it most probably is being caused by
a service running in the background. Boot the
PC, open Task Manager and see what you have
running. Then one by one, remove/disable the
services and retry. Eventually you should find
the one that is causing the problem.
