This computer is fast and very quiet. When I first got it the DVD drive would not work but the seller sent me another one ready to install. No problem with installation ,it was very easy. I bought this computer to upgrade to windows 10 even though  I did not want to and learning how to navigate around on windows 10 in a pain but I will get use to it.  I was disappointed at first because of the DVD drive not working right but the seller stood behind the sale and fixed that. I am happy now  I bought this computer.
