Wifi not showing up on PC after power outage

[SupportPlayPalace]

My computer does not show any wifi at all. I tried everything i even replaced the pci express wireless card with a new one and it is still not working. Someone help me please....

Is the wifi showing up in a cellphone? The router could be bad.

Or the PCI slot could have blown (or the southbridge chip on the motherboard, or a lot of other possibilities - you have to narrow it down).
