Had this PC about 4.5 m.  Was working great, fast, and doing things I wanted it to do which wasn't much.  I waited to transfer files bc the last PC I purchased from Blair was DOA.  I used this one to surf bc it was so fast, I had it side by side with my Dinosaur Dell that works but really slow to search.  But on April 10th, I turned off the power to change some things around, and then turned it back on, and bingo it won't stop running- it is making a continuous loud fan noise, a blank screen, and the power button flashes.  Not worth the trouble, I'm NOT a techy, I want something that works without looking under the hood.  These are crappy refurbs.
