I have a friend who bought a new PC and is giving me the parts of his old PC. I have prior knowledge to building PC's. I have a decent PC but my motherboard and processor are lacking while his old PC's motherboard and processor are a step up from mine. So, I was wondering if I could take his motherboard and processor and put them into my current PC. Would it be a simple swap or would I have to do anything else besides taking out the old and replacing with the new?
