sleep/wake up problems

Hey all,

 

I just built a new machine with the following config:

 

- B450M Mortar (updated to newest bios: 7B89v13)
- AMD R5 2400G APU
- 16GB (2x8) G Skill Aegis 3000Mhz RAM
- Be quiet! pure power 10  600W PSU
- Philips 276E8VJSB 4K IPS Monitor (connected via HDMI)
- Windows 10

 

Everything works fine after updating to 1.30 bios and installing Adrenalin 19.1.1.
But two things are confusing me:

 

1st issue:
The machine doesn't wake up from sleep mode correctly.
My monitor stays off.
Motherboards LEDs turn on and the CPU fan starts spinning.
The CPU debug led lightens up.

 

Got to press the reset or power button.

 

Clearing CMOS brought no result.
Reverting to previous bios didn't help.

 


2nd issue:
I set Win10 to turn off my monitor after 5 mins of idle.
But after it turns off, it turns on again immediately and shows a black screen.
I can return to windows by moving my mouse or pressing a key on the keyboard.

 

I tested my monitor with my laptop and it went off without any problems.
So it seems to be a problem of my new machine.

 


Does anyone know whats wrong with my pc?

 

Thanks
