Original computer arrived 2 days earlier than anticipated, worked ok for about a week, then blue screens kept coming up saying there were problems.  Also said there was no hard drive, but obviously there was.Called tech support, guy went in my computer remotely & fixed it from there. Worked ok for another week then same thing happened. Called tech support again, told them I would either like another computer or a refund.They sent me another one within a few days & a return label for the first one.So far it has been ok, if this one goes wrong I will request a refund. I was very impressed with tech support in India, very knowledgeable & helpful & polite. Told me to call again if I needed any assistance at all.
