Hi,
I'm working on an HP Pavilion 7960, trying to determine what the problem is. Here are the facts:
1)When the computer is turned on, the monitor does not respond at all. It's as if it's not hooked up to anything. I know the monitor is good because it works fine on another computer.
2)I have a mouse that lights up when it has power going to it from the MB on another machine, but when hooked up to the USB port on this machine, no lights.
3)The same problem exists with the USB keyboard: no lights when on this machine, whereas it has the typical keyboard lights when plugged into another machine.
4)At first I figured this was a problem with the power connection on the MB, as the video card and USB ports weren't getting the power to run their respective components. But then I noticed that the power light for the computer was on, and the system fan and CPU fan were running. All three of those things are plugged into the MB, and use power from the MB.
5)I believe the devices that plug directly into the power supply are working fine, as I can hear the hard drive spinning.
So in a nutshell, I've got some devices getting the power they need from the MB (power light, fans), and some not (USB ports, AGP video card). Could this be a problem with the MB not being able to pass power to certain devices, or what? What is the suggested remedy, or further diagnostic tests? Thanks for any help!
