Alarm Clock Notification Delay on Windows 10 Pro

Hi, I just finish building my custom pc and have updated the drivers. But there's one problem I'm currently having, the Alarm in the built in Alarm & Clock app didn't go off on time but instead the notification was delayed 2 - 3 hours later after I wake up and moving the mouse. I usually left my pc on overnight.

I have tried:

• Resetting the Alarm & Clock app.
• Reinstalling the Alarm & Clock app.
• Resetting the PC.
• Turn off anything that puts my pc to sleep in the power settings.

Unfortunately nothing works.
I do know there's a a free third party software for alarm. But if its possible I would like to use the built in app because I never had this problem before on my old laptop.

Thank you.

Nope, my monitor is still on and idle, even my wallpaper engine is still moving around. So I don't think my PC is asleep. Its just the alarm notification being delayed for some unknown reason.

Guess I'll stick to the free alarm clock hd+ app.
