Question Display won't turn back on after being idle

[Cryptus]

So my display refuses to turn back on after being idle and therefor turning off the screen. The two scenario's where this happens is after the display turns itself off after being idle for too long or I turn the display off and on (Nothing happens when I move the mouse).
I am then forced to restart my pc manually.

I tried:

• reinstalling my graphics drivers
• reinstalling my display driver
• reset my monitor
• clean the RAM
• clean the GPU
• checked the settings in the power settings
• tried several minor fixes on the internet

in the idle scenario I sometimes hear 4/5 bleeps.
in the off/on scenario I sometimes get my screen back on without the mouse visible.

On startup everything works just fine.
So I am a little confused what's causing this problem.

PC specs:
CPU: Intel i7 6700k
GPU: Nvidia RTX 2070S
Motherboard: Gigabyte ga-z170x-gaming 5-eu
RAM: HyperX 16GB DDR4

Bleeps? Are these from your computer or from the monitor?
What monitor you got?

Beeps are coming from the motherboard I assume. The monitor is a 27" BenQ XL2730Z 144Hz 1ms

Can you describe the beeps in more detail?
Which beeps are long, which beeps are short?

There are 4/5 short (about 2 a second) beeps most of the time. One time I had several rapidly beeping.

Hmm the things I think you should do you’ve already done.
Maybe reset the CMOS?
I’m definitely not the biggest techie around. I might need someone else’s help in here as I’ve never used a gigabyte motherboard or experienced a problem like this in my life.
