Power mac G5 won’t power on with usb keyboard.

When the usb keyboard is not plugged G5 power on with chime. But when I plug in the keyboard I and press power button it just click as trying to start. Pressing the power button all I get is clicks. I tired with 3 different keyboard all mac. Two different in the pic and one white aluminum extended keyboard. Any idea what’s going on?

Turns out it was video card causing it. When I remove the video card. It power on normally with chime and ubs keyboard connected. Do I need to get new video card? It was working before it took it out to clean it.

Perhaps the video card just needs to be re-seated, i.e., re-installed properly. It is possible that some of the pins were misaligned earlier, especially if this is a G5 with an AGP slot (which included USB-related pins).
