Summary: never worked optimally, has something missing internally so I cant defrag. I called the Dell people for assistance paid $129 to fix the problem (because if you do not defrag, your computer runs slow,) The problem was never fixed. Still runs slow, freezes up and it is very frustrating.
It was like a loud humming noise which got very annoying
26 February 2015
Summary: This tower worked really well at first for about 3 weeks. Then, it started making this noise whenever I turned it on. It was like a loud humming noise which got very annoying! To finally, it stopped working all together. All my USB ports stopped working! ! I couldn't use my mouse or keyboard.
Summary: The condition of the computer was not up to "refurnished" standards. Can't update windows, every time you turn on shows a black screen. It's not in workable condition. We are returning this product.
