Hey all, My 3 year old MacBook just got a new- replaced under AppleCare hard drive about three weeks ago. However, since then, the computer has been extremely slow. Programs won't load/close, websites are slow, stuff crashes all the time. I haven't been hardcore gaming ar anything, just Chrome and Word. Just wondering if any of you thinks this has to do with the hard drive, and if I should contact Apple before my warranty expires on Monday.
