First off, the RAM was not the RAM that was in the specs of this PC. They resolved this by sending me the proper RAM, free. This is above and beyond. They were great to correct the problem. My PC runs like a champ. But I have to finish explaining exactly what's going on.  In advance I want to say as long story short before I explain my situation, I got to keep the RAM that came with the system plus they gave sent me RAM that was supposed to come with it. Everything works awesome! Happy right now. If you have an issue they'll take care of you. They never once shot me down after I called 6 times to try and get the specifics worked out.Regarding my situation, they offered to help me replace the motherboard with a better one because of how dissatisfied I was with the computer overall because my current PC was better in performance and power....I honestly had no idea that HP customized their motherboard and power supply to make universal components incompatible. In other words, the HP elitedesk is strictly an office desk computer, Nothing more. Do not expect to modify or enhance this PC for entertainment. Honestly, I thought it(the motherboard/mobo) was like any other computer. As I said, my computer I had for years currently had way waay out performed that computer, but has older hardware. I simply took the best components of the HP Elitedesk(EliteOfficeDesk computer) and put them into my original computer. Processor, RAM and motherboard was important. The SSD was nice additive. I just went ahead and ordered a better motherboard than the one I have which they offered to help me replace and then I added the components from my original PC, combining them all together to make my PC awesome. So basically, the HP tower, board and power supply just ended up going into storage or I'll give it away. But in the end the value came out quite close to cost of upgrading.
