Sometimes when I turn on my computer the screen area settings have changed without me doing anything. They go from 1024X768 to 640X480 pixels. Do you know why? I’m running Windows 98 SE.

Possibly a setting in Windows instructs it to default to 640 x 480 x16 each time Windows starts. You can find this setting by going to ‘Start’ menu > ‘Run’ and typing in ‘msconfig’ (without the quotes) followed by clicking the OK button. In the application that opens, click the ‘General’ tab then the ‘Advanced’ button (in the bottom right hand corner of the box). In the ‘Advanced Troubleshooting Settings’ box which appears, you should see an option that is labeled ‘VGA 640 x 480 x 166′. If this option is enabled, disable it which should fix your problem. Don’t modify any other options though because that is for advanced system administrators only and serious damage can be done if you use it in the wrong way. I also apologise for the time it took me to respond to your query because it took some time to research.
