I've purchased 5 different refurb computers Off Amazon. The First 3 worked great. The last 2 I ordered couldn't possibly have been refurbed. No way anyone tested them or they wouldn't have shipped them. Both had similar problems, the main being the video cards didn't function. The screen flickered, and rolled. Video was limited to a 3 inch column in the middle of the screen. This one also had a "Rear Fan Failure" warning I could barely read due to the faulty video card and the hard drive clacked with every rotation. Seriously, I don't have time for this. I guess the company expects just ships bad computers and expects someone to get stuck with it?
