I just order from Apple Store and been using my Mac Pro for only 1 weeks. It hasn't been abuse or anything. I alway turn it off everytime I go to sleep or to work. Today when I come home, I press the Power Button and nothing happend! I freak out and got mad at the same time. I try unplug everything and the powercord, and let it sit for 60 Second to reset itself and plug back the Powercord. It now turn on and everything seam fine. But my concern is that I pay more then 2 grand on this Machine and it freak out on me in 1 weeks. Should I call Apple Store about this or even replace with a new one? It just strange that it does this and I'm not very happy about it. I'm scared I may get a defect one and in the long run it die quicker? Please give me your advice. Thanks!
