I have set my W10 so the screen turns off after 15 minutes. (The PC is set to never go to sleep.)

I have set my W10 so the screen turns off after 15 minutes. (The PC is set to never go to sleep.)
Normally, a shake of the mouse or pressing a key will turn the screen on and the PC becomes useable.
Several times over the last few weeks, after the screen shuts off, nothing will get the screens on again. (I have two Dell Ultrasharps).
No USB ports have power. The illuminated keyboard is still lit but unresponsive. When its USB is unplugged and replugged, the keyboard is no longer lit and still unresponsive. I have swapped the screen ports around - no difference. Opening the CD drawer still works but does not reactivate the PC. A CD will spin up but not reactivate the screens or USB ports.
The only way to rectify is to press and hold the power button on the PC.
The motherboard is 5 years old and is kept clean. No other issues are detected.
