I bought a used computer for a friend that had a pirated copy of Windows 7 on it. I'm about to go buy a legal copy of 7, but the computer didn't come with any motherboard installation discs. Would I be safe to reinstall windows? I ask this because from what I remember when putting together my own computer, I had to install the internet drivers from the motherboard disc to even get online to download the rest of the drivers. I'm afraid about installing a legal copy on 7, not having the drivers, then being unable to do anything further.
