It would help us help if you could take the time to describe the problems with the PC in detail. If you have a Recovery CD the most expedient course might be to Recover it to factory condition. This will eliminate all your data so you might want to back that up to DVD/CD first.
Outside of that why do you want to connect your laptop to this machine?
Connecting a new laptop up to a
messy PC doesn't make much sense. Fix the mess first which a Recovery installation should do.
Medion may have Recovery details if needed:
