As soon as i plugged in my gtx1080 my wificard stops working

Specs: Windows 10
I bought my gtx 1080 today and I plugged it into my pc, but when I booted up my computer, I had noticed that my wifi card stopped working. I started to check if everything was fine and everything is nothing is fried or dead, but when I plugged my wifi card in the slot above my GPU it would suddenly work(i have an APU so I can boot up without the GPU). But my GPU wasn't being detected at all. I think my problem is something wrong with the PCI-E slots because my wifi card isn't being detected in my device manager.

CPU: Ryzen 5 2400G
Motherboard: Gigabyte AB350-Gaming3
GPU: Asus ROG Strix 1080
WIFI-Card:TP-Link n900
PSU: PowerSpec 650 watt bronze 80+

A while since I played with windows kit... but I recall that there was design situation on atx etc. boards where the default/designated slot for an add in graphics card shared an irq with the adjacent card slot. One could use either the graphic card slot or the adjacent card slot; but not both at the same time.

Perhaps this the situation here? Have you tried putting the wifi card (which I am presuming is an add in card) in a different slot; so that there is at least one empty slot next to the graphic card?

Please post the make/model of the CPU, motherboard, graphics card, wifi card, & power supply.

Also what motherboard?
Some motherboards due to limitations on the number of PCIe lanes shut down certain PCIe slots when certain others are in use. Make sure that your GPU is in the top most PCIe slot marked 16Xslot at 16X bandwidth. If there is a second PCIe slot marked 16X at 8X then it shares lanes with the 16X slot and they both become 8X slots when both are in use. Some have 16X slots at 4X and they often share the lanes with two to four 1X slots and either the 4X or the 1X slots are disabled when the other is in use. This means that with one of these boards if you have a PCIe SSD on the 4X slot then you cannot use the 1X slot for a Wifi card or other things. If you use the 8X slot for the PCIe SSD then the graphics 16X slot becomes an 8X slot, thereby limiting the graphics performance.
Later chipsets have more PCIe lanes so are less limited.
Read your manual carefully and/or post the exact model number for further review.

You have to be a little bit crazy to keep you from going insane.

I have already done this but still no sign of the wifi card anywhere and I just added the names of the hardware I use

The graphics card should be in the PCIex16 slot. The wireless card can be used in any one of the other PCIe slots, it doesn't have to be an x1 slot. Have you experimented? You probably need to adjust some BIOS settings too, such as disabling the onboard graphics.

You should seriously consider replacing the PSU. PowerSpec is a MicroCenter house brand & not a very good one. http://www.tomshardware.com/answers...
