You need to finish the repair by starting an installation, then selecting "repair an existing Windows install" during the wizard. That will repair the corrupted drivers and the registry keys. You'll need the activation key (on the label) and then re-apply Windows updates. You will keep your installed software, though.
BSODs are never good, crashes like that don't get to safely save system files that are in use. Too many of them and you'll need a repair install, like I described above. Most likely some corrupted files rendered the KB and mouse useless.
