We are new to the forum. We bought our son a pc from PC Specialist for Christmas and have been unable to set it up. We didn't try it on delivery as it was for Christmas and now it has been ruined. We plugged everything in as per the instructions. We have made sure that the monitor is plugged into the graphics card and not the motherboard but it is not receiving signal. Unlike the other posts I have read, nothing is powering up on the pc. The only light that is on, is on the motherboard. There are no beeps, no fans powering up, no nothing. Obviously PC Specialist is not open - am I missing anything obvious?
