When I first got the computer and set it up, Windows wouldn't load. I had to call tech support for instructions on how to redownload Windows from the boot menu (luckily I knew what I was doing), but after following instructions exactly I ended up having a tech person come to my home and said the hard drive that was in the computer was no good. After I got a new hard drive I haven't had a problem. For what I paid, I'm not complaining, but they should be tested before being shipped.
