Hi, I have had my Alienware X51 R3 for about two weeks now and have had this problem for the past week. When I press the power button on my pc in the morning, the light on the power button lights up, but nothing else happens on my monitors or in the pc. If I switch it off at the wall and then back on again, I am able to start the computer. I have had 5 phone calls with three different people at Dell technical support, but none of the settings they have told me to change have done anything. I have an Intel i7-6700, NVIDIA GTX960 and a 330W adapter. Does anyone have any ideas? Thanks
