I have a HP Pavilion Elite - HPE-560z. The power button no longer lights up and there is no video going to the monitor. I plugged in another working monitor and same thing. The PSU light comes on, motherboard light comes on, case fan spins, CPU fan spins, video card fan spins, and the light on the mouse lights up. I took the video card out and plugged the monitor into the computers' VGA connector and still nothing on the monitor. I disconnected the hard drive, cd drive, video card and RAM - still nothing. I thought I would atleast hear some beeps. Nope, same thing happens.
I was thinking it might either be a bad motherboard or a bad CPU. What do ya think I should do?
