Didn't have this product for a year, and had to send it back to get it service.  By the time I got it back had already purchased a new one.  Didn't use until 6 months later, when I plugged it in was working for 30 minues and start hearing the noise and would not come on anymore after that.  Sending it back again to see what the problem is again, we will see what happens this time. Would recommend not to purchase computers from this seller.
