The monitor frequently turns off and on without reason...
In short, you’re dealing with a gadget stopping the system from powering down or turning off the screen. It could be the hardware itself or its control software. This might involve your printer, a missing or broken driver, faulty hardware, or a peripheral. Check the Device Manager to verify all devices are enabled and there are no disabled items or warning signs like yellow “!” lights. If your computer wakes up immediately after changes, run powercfg /lastwake—it shows which device last activated. If it still doesn’t work, try removing any unnecessary drivers or software, then test again. For a simple fix, use basic USB keyboard and mouse, disconnect everything except essentials, reset hardware, remove drivers, and restart.
