This problem has been happening for awhile now, after an amount of time without any use my computers monitor will turn completely black, it will still be on as the mouse is visible and I can still move it but if this happens it requires a full computer restart to bring the screen back, it's quite annoying as this happens several times a day. I have all of the timers set to never have the computer sleep and have tried many other options. I have a Dell Inspiron all in one desktop computer with windows 10. Any help at all would be greatly appreciated, I've struggled with this issue for a while and can't seem to find a way to fix it. I can provide any other info if needed.
