I reformatted my PC a couple of days ago and it was fine for awhile then after sitting idle for awhile the log in screen came on. Now it happens when I sit here for a couple of minutes. I found a way to turn it off when I first bought the PC, now my notes do not work. I have found all kinds of ways for turning it on, but nothing to shut the display off permanently and I know it can be done. I have screen saver set to none, sleep and hibernate set to never. any suggestions.
