Monitor is connected to the CPU = Nothing!

Hello,

Ok I have a HP Pavilion Elite m9060n Desktop that has just been moved from Italy back to the States and when I set everything up and press the power botton all the internal fans start up, green light on the power unit, the disc drive works but the Monitor is still black. The USB and cards seem to have no power.

No indications, or alerts (HW Beeps).

I opened the CPU up and all cables appear to be connected to the correct slots. Only spent a few minutes T/S'ing it. So I figured I would submit this question to see if anyone else had the same problem and what your fix was.

Thanks for the help... Hoping that I do not have to buy another motherboard or build a new computer
