Jack for internet connection died first (after 90 days of course) and I had to install a wifi card - ok, that's not the end of the world. Then just short of one year one of the motherboard drive channels died and took the ssd with it. Worked from an external drive for a while which is miserable because I had to reinstall all of my programs (no, I did not have a good backup). Now the unit won't even go through the bios check. Maybe this was just an exception to the quality of Dell and refurbished equipment but once burned, twice shy. I won't go this route again.Contacted the vendor for help in getting Windows activated with the new motherboard and they got me set up immediately over the phone. I had the new activation code before the phone call was over. I had also contacted the vendor via Amazon and to my surprise they offered to exchange the PC without consideration of being well past the warranty period. All I can say is ten stars for the vendor even if the PC didn't rate the same.
