Purchased this computer in March for my business as my old unit was slowing down. It worked great but only lasted four months then began making a beeping noise and would not turn on. I contacted seller and was told since this is a refurbished model it was no longer under warranty and was sent a you tube video to try and fix it (which did not help). Took it to a local cpu repair shop who basically told me it was junk and would cost more to fix than I paid. Huge inconvenience for me as I use it for work.
