|Describe the system/model you have.|
I doubt any windows 98 computer has a restore partition, as do newer computers, that allow you to boot to it and restore the OS. If you know differently about your particular model then the way to do it would be in the manual for that model. In lieu of that, to revert to 'factory settings', you need that model's restore disks or a regular 98 installation cd.
To get wifi on 98 the computer will need a wifi card (as far as I know no 98 computer came with built-in wifi) with 98 drivers so the card is properly setup in device manager.
The games may not be loading because the cd drive is bad or the games are not compatible with 98.
You've got an old computer. Don't expect it to do what a new one will.
