A friend is having computer problems and I’m going over to his house tomorrow to see if I can’t straighten it out. From his description over the phone he doesn’t have a restore CD but it is not a custom made computer. Smaller manufacturers often put a restore folder somewhere on the computer but I have never dealt with one. Where would I find it and how do I use it?

It is an older computer with the original Win98 installation. Lots of illegal operations and lockups but evidently not BSODs.
