I've recently treated myself to a Asus ROG Maximus Hero XII and an Intel Core I9 10900k and a shiny new monitor, a ROG Strix XG27UQ.
No other components in my system were changed and I've done a fresh install of Windows to keep everything happy shiny.
Not long after doing the ugprade though, the motherboard no longer detects my GPU (an Nvidia 1080ti) on boot, I get one long beep and 3 short meaning no GPU detected.
After a few seconds, windows will boot up, the GPU is detected and everything works nicely.
This will happen consistently if I restart Windows, and intermittently (more often not than it does) on a fresh power up.
I never had a problem pre-upgrade, using an Asus Z170 Sabertooth Mark 1 and an I7 6700K.
The strange thing is that after I did the rebuild, it was working fine and this has only recently started happening.
I've tried moving the GPU to a different slot on the mobo, I've tried only connecting 1 of my 3 monitors but neither of these make a difference.
The BIOS is set to use PCIE as the first GPU so there shouldn't be a problem there.
I might be entirely wrong, but could this be a problem with the PSU? I'm using a Superflower Leadex Gold 1000w "80 Plus Gold". I was under the impression that this should be more then plentiful to run the system.
Providing I am wrong about this, what could the problem be here that's causing this issue?
I don't know whether it's related or not, but I'll mention it anyway. I've having a helluva time trying to get my Oculus Rift CV1 working on this system as well. While the Oculus software shows everything with a green light, as soon as I start to use the headset, it intermittently disconnect and various sensors will start turning orange to show that it's not got a good connection or show as USB 2....despite all the ports on the back of the PC being being USB 3.1 or 3.2.
