Here are some notes I made on what you may need. I hope they are what you are looking for. Cheers,:-)
I take it you can no longer use this computer so the only way forward is to format and do a clean install. for this you will need a windows start-up disk (floppy).
if you have a start-up disk respond and i will explain how to format your computer and re-install windows.
if not you will have to use your wifes laptop (as long as she is using win98 too, if not
go to "start/control panel/add remove programs", click the start up disk tab at the top and click create start up floppy, follow the on-screen instructions
TO FORMAT YOUR HARD DRIVE
Reboot your computer with the startup floppy disk in,when you get the boot menu options choose "start without cdrom support"
this will create a virtual drive which will probably be drive D:
At this point if you type D: & press enter the prompt will change to D:> type "format c:" dont forget the space between format and c:, press enter then wait. once the format is complete, press enter to complete the format
TO INSTALL WINDOWS
reboot your computer with the startup floppy disk and your windows98 cd rom in the drives, when you get the boot menu options choose "start WITH cdrom support"
once it has finished loading
your cd will be drive E:
at the prompt A:>
type E: & press enter
the prompt should change to E:>
then type setup & press enter
this should start the windows98 setup
this will ONLY work with a Full windows98 disc, it will NOT work if your windows98 cd is an upgrade.
Have you checked that the cd is not dirty. if it is clean it and try again (to clean the disc GENTLY wipe with a soft tissue in a circular motion round the disc) do not use any liquid cleaners.
if you have a problem post back and we will try to help again
