Hi.
I am right now helping my friend install a GPU over webcam.

He have installed the GPU in the mobo and connected the pci express connectors, but
when he turn on the computer no fans start to "fan" and no display on the monitor.
we tried taking out 1 pci cable and the fans turned on, but no display.

His old GPU still worked.

New gpu: gainward gtx 560 non ti
old gpu: 240 from nvidia.

im am not aware of his other specs because of his lack of knowledge when it comes to computer hardware.

do anyone have any ideas on how to fix this?

thanks in advance
