This is the most unstable computer I have ever owned.  I get a blue screen of death multiple times a week (Sometimes multiple times per day) and have to constantly chase down solutions.  It seems like I spend more time trying to keep it working than I actually spend using it.  I wrote to the customer service and they were helpful in giving me suggestions of what to update to resolve the blue screen error I was getting and when I followed those instructions it worked for a bit, then the computer started giving me blue screens with different errors.  When those are resolved, new problems pop up.  If you want a computer that will just do what it is supposed to do, do not buy this computer.  If you don't have any serious work to get done and just want to wastes hours trying to make your computer work, this is the right purchase for you.  I do not know if this is because it is a refurbished computer or if it is just the way this model acts in general, but if I had it to do over again I would have never made this purchase.Update Nov. 1, 2020:If you buy this computer, definitely get insurance with it.  I purchased insurance with mine and I am so glad I did. In September this computer started a crash/restart cycle that I could not find any way around. The start-up repair function could not fix it and the computer couldn't even complete a factory reset before crashing and restarting.  I sent it is for repair under my insurance plan and the hardware was so faulty that after they ordered parts to try to repair it, they ended up issuing me a refund for the price of the computer because it was too messed up to be repaired.  If the hardware was so faulty that replacing it made more sense than repairing it, how did it ever get cleared as a certified refurbished product?  I bought this computer from "PC Server and Parts Certified Refurbished" and I will never make the mistake of trusting them to supply quality products again.  As I have said before, this computer has been a constant headache.  I have now missed out on 2 months worth of work for which I purchased this computer.  To be honest, I am glad to be rid of it, but the loss in productivity it has caused me is the most disappointing part of this whole experience.  I will say it one last time, avoid this seller and this computer if you need a dependable computer.  If you decide to go for it, definitely get insurance.
