I moved about 6 weeks ago. Packed up PC, monitor, printer, etc. in box. Last night, pulled it all out, plugged it in and everything works except the CPU. The monitor turns on, printer has power, surge strip seems to be supplying all with power........I have pressed and held the power button, switched the power on and off in the back of the CPU and don't know what else to do......can anyone help me? Will it ever work again?
