Hi,
New PC (built a few months ago) with old video card (GTX 1070). I did a clean install of Windows 11 from USB drive. Everything works fine now except that I can't get the video card working reliably. Yesterday, if I start the PC with the monitor connected to the video card (DisplayPort), I got black screen. If I connect to the motherboard graphic, it works fine. I did a hot swap to the video card with Windows 11 running, it worked. I even tried to restart a few times, shut-down and power on, connecting to the video card. Everything was fine. So I thought the issue was resolved.
The same issue happened again this morning. The video card just won't work at startup. I had to switch to MB graphics first. Really weird.
I got the latest driver installed. No "unknown device" in Device Manager … everything looks normal.
Please help... Thanks!
