Win2K is more forgiving than you think. You can even go to the Add/Remove Hardware wizard and remove those Question Marks with "Unknown" against them. Best thing I did, once, when I had Multiple cases of a CD R/W Drive and the poor thing didn't know which one it was supposed to be host to.
Turned out that I deleted the Motherboard and all its offspring so on the next boot there was a protracted series of discovering hardware (of course all the drivers were there) and at the end of it the machine was much more sprightly and the sole CD R/W was happily accepted.
Its fun to delve into the unknown like this because you're not losing data and you can have some pleasant surprises.
