System starts with Windows but screen remains off.
Hello everyone. I recently installed a new PC and everything worked smoothly yesterday and the day before. Today, after booting up, the computer functioned correctly, but my monitor isn’t showing any signal. I removed the GPU and connected the DP cable to the motherboard, yet there’s still no output. The motherboard displays debug lights, but none are active. After some waiting, I logged in using my credentials and pressed ALT while holding random keys to verify I was in Windows. I can hear the system sounds, confirming it’s running OS, but the monitor isn’t displaying anything from the GPU or integrated graphics. My specs include an I9-14900k RTX 3080, 32GB DDR5 RAM, 5600MHz PSU, and a 1TB M.2 SSD. I’ve followed all standard troubleshooting steps—reinserted RAM, used one stick only, reset the CMOS—but nothing resolves the missing display signal.
