Boot only from PC with two monitors.
Boot only from PC with two monitors.
I switched from two monitors to one a few days back, but it didn’t boot properly to Windows. I could enter BIOS but only saw the Gigabit logo and no system started. The fans were spinning, and I realized the PC wouldn’t run unless I connected two monitors. When I swapped everything—RAM, GPU, graphics card—I got a smooth start every time. We tried connecting one monitor via DVI and HDMI, but it still worked only with two monitors. I’ve also tested different monitors, but the specs are the same: i9-9900K, 32GB RAM, Gigabit, AU-390. It might sound crazy, but what would happen if I used one DVI and one HDMI port on the same screen?
Connect the device to the computer and run the driver installer. Ensure you're offline before proceeding. If Windows starts without a driver, it may indicate a hardware problem.
