I really don't understand computers, but so far this is working perfectly for me. It has started up everyday, and that's really all I ask in a computer. I had to contact tech support and was immediately helped with my issue. The computer itself looks brand new, internally there wasn't even a spec of dirt or dust. Sometimes it is a little slow to start up, but other than that I am happy. It came with a booklet of support, that in itself impressed me.
