No signal on monitor / black screen after showing motherboard logo

[Newtech1]

Let me explain what happened,

I send my monitor for repair in service center, and I stopped using my PC after week monitor came from service center then I connected my PC.

I hit the start button gigabyte motherboard logo shows up after it monitor showing NO SIGNAL.

I thought it's connection problem then I used another HDMI port for connection but still showing NO SIGNAL after gigabyte motherboard logo.

 

I did everything I could nothing worked. Finally I re-installed window 10 and it worked but it showing low resolution.

So I installed GPU Driver  (Adrenalin 2020 Edition 19.12.2)  after installing it says restart your system so I did

But again It's doing same thing gigabyte motherboard logo shows up after it monitor showing NO SIGNAL / Black screen

 

I'm guessing it's a GPU or Driver problem but I'm using  AMD ryzen 3 2200g

I'm not using external gpu I.m using internal gpu

 

My PC spec

AMD ryzen 3 2200g

8 GB RAM

GIGABYTE B450

 

Please Help me

Connect it to a tv or something else. See if the problem continues.
