I then decided to check the sleep timers with the 'powercfg /waketimers' command but nothing shows up there. 5 minutes later, same thing happens with the display and after 10 minutes, system just keeps idling instead of going to sleep. Checked 'away mode', (my system is set to performance mode since it's overclocked but I tried balanced and away mode, the result is the same) I set display timer to 5 minute and sleep timer to 10. I then started going through AI Suite's EPU settings. It just turns back on as if something is preventing it. Display turns off, then it goes back on after a few seconds for no reason. I usually use display turn off timer too (I just disabled to test the sleep timer) and when I tell the displays go to sleep (let's say after a minute again) this happens.
After 1 minute, literally nothing happens. To test, I disabled display turn off timer and told the computer to go to sleep after 1 minute (from windows settings). I also have AI Suite 3 installed (latest version with the latest patch for my motherboard -Z170 Pro Gaming-). I've been having this problem since I built this system.
