When I was fiddling around with ethernet earlier today, I decided I didn't want to install and use it. So afterwards I unplugged the ethernet cord and went on with my day. I use a PCI express wifi card for my internet. I forgot to plug it in after I used ethernet. So when I went to install it (my computer was on) my screen flickered and then it went dark and it said I had no signal. Neither HDMI nor Display port work on any ports of my GPU. I tried rearranging my graphics card in my second PCI slot and it still doesn't work. Neither does my PCI express wifi card work either. Did I short circuit my motherboard or GPU or both?
