Yesterday morning I was plugging in my VR headset's displayport and I brushed against the adapter to my monitor. Without going into to much detail I thought it was the adapter then I thought it was the cable, and it was neither of those. I decided to use my old GPU since I thought my current GPU was dead. So I plugged it in and when I plugged it in my monitor still didn't work. I then thought it was my monitor so I used my TV and that also didn't work. I've come to the conclusion that my PCI-e slot is dead, and since I can't access my other PCI-e slot I may just get a new motherboard. However, just to be sure, how can I fully assure myself that it is my PCI-e slot that is broken? Or is it really broken based off of what I described?
