Hey, so I plugged my GPU into my friends pc to help him troubleshoot and when I went to plug it back into my pc it wasn't posting and I was getting error code 99 on my ASUS motherboard. I tried every port and nothing was working, so I rebuilt my pc and reset the CMOS as a guide told me to. After this, it still wasn't posting with any port but the HDMI.

my specs are:
I7-6700K
ASUS MAXIMUS HERO VIII ALPHA
ZOTAC 1080
16 GB 3200 HYPER X RAM
120 GB SSD
1TB HDD
650 WATT PSU
thank you in advance for any help :)
