Your system is running, but neither monitor is displaying anything.
I’ve completed most of the optimizations in this video. After restarting the PC, the main monitor briefly turned on before going black. It detected itself in the display settings when I checked the second monitor. This morning, after turning it back on, both monitors still showed the same issue. When I power-cycled the system, the desktop and other components worked temporarily. Restarting with internet access allowed Windows to download drivers automatically. The main screen faded briefly before shutting down. After reinstalling Windows, the main monitor eventually came back online, but the second monitor remained unresponsive. I removed the cable and reinserted it, which briefly restored the display for a short time. After resetting CMOS and clearing BIOS settings, the problem persisted. I tried disabling antivirus software, but found no solution online that helped.
I suspect you might have disrupted the display driver while watching that optimization video. Also, avoid disabling Windows Defender through the registry unless it's your sole antivirus solution. The safest approach is to back up your crucial files. Delete the boot drive and reinstall a new Windows version. This should resolve any issues that caused the display problems initially. If the problem persists, it could indicate a faulty graphics card coinciding with your changes. Hope this assists you.
