I'm really disappointed with what's happening to me.It's been a month since I received my pc, and when I try to open it, the machine works but doesn't display anything. I contacted the service, they asked me to return the product without any assurance that it would arrive safely and on time. I looked for the solution on the spot by myself, the problem came from the ram card which when I remove it the pc works correctly. I then had to buy a new ram card, but unfortunately the same thing happened: black screen.Now I'm confused because I've lost 4GB of ram, even though it was because of the amount of ram (8GB) on this PC that I agreed to pay for this machine.
