I recently installed a new power supply and graphics card on my desktop. i have them working great, however, the wireless adaptor card has stopped working. The question is, could I have removed power from the pci slots when I installed the power supply? The network card worked fine last night, but I turned the machine on and it does not even see the card anymore. I took some steps, uninstalled the driver and card, then reinstalled the card. Downloaded the new drivers, and attempted to reinstall with those drivers but nothing, So is the card possible bad or is the pci slot not getting power?

Try a different PCI slot with wireless card. It and video card may be trying to use the same IRQ or address and neither one can share an IRQ.

If that doesn't work and BIOS allows you to reset ESCD, remove wireless card, reset ESCD, install wireless card, and reset ESCD again.

... the PCI slot has power. When you plug the power into the board, The entire board is powered.

Did you check to make sure the card was seated securely?

Do you see anything in the device manager? Does it have a yellow exclamation mark on it? Any other devices have yellow or red marks?
