Can I just skip re-installing the OS, and just install the new drivers?
Negative.
I don't have a copy of my OS, so i'm SOL if that is the case.
U give up too easily.
If you have the tenacity

Get hold of your license#, there is a couple of tools to query this if you have lost it, GOOGLE. Download an generic image of you OS, again GOOGLE. Must the the exact, whether W7, W8 and what not and 32 or 64bit, Home or Pro. Make it into an ISO and create yourself a Bootable Flash, and install from that. After installation it may complaint at registration but that can usually be resolved by calling in a special ph# (popup screen tells you) and going into a somewhat tedious automated registration procedure.
All this can be too...
