This is the second refurbished computer I purchased from Amazon, No problem with the first one.The replacement hard drive started making noise within about two months  on start up and with in a few more months made noises all the time. (My wife asked why it was humming so much and I said it did not know the words)  Then it started giving off a eye irritating fume caused by whatever is used to make plastic flexible.Really!  Look that one up. Bottom line I tossed it yesterday.Not asking for a replacement or refund. Just found it unusual and passing it on.
