Sometimes blackscreen/no connection after bootscreen

Hello everyone,

I have a really strange thing happening and i cant really find people with similar problems.

Some months ago i bought all hardware for my self built pc, pc didnt work properly back then (ram were both
faulty says the shop, and they replaced motherboard, both checked by them for faults). Then when i built it
again it worked like a charm and didnt have any BSOD or any crashes whatsoever.

But since the beginning (after the replacements parts that are checked) my screen sometimes stays black.

When i boot my pc up you see the MSI boot menu with the W10 loading icon, but when it normally switches to the W10 password screen. It just goes black, my screen loses connection and the light goes orange. When i switch it off and on it stays green (guessing it has connection) but doesnt show anything at all. Now i ofcourse just reset my pc and then it just works with no problems (resetting with power button and just turning off PSU) my pc has no issues at all and works perfect.

Now some things worth noticing.
-Sometimes if i let it stay long enough on black screen the screen pops back up, i can even put in my password when it is black and pops back up. I can blindly log in.
-Sometimes it just doesnt pop back
-It is connected with Display port
-No buzzing sound or debug leds, looking into the case its just working as if nothing is wrong

This does only happen sometimes, perhaps like 1 on 5 times booting it up, doesnt matter if the pc is off for 5 minutes or 5 days. Mostly it just works, but sometimes it just stays dark.

PC info:
G4560
2x Hyperx Ram
GTX 1050 Ti Gaming X 4G
MSI B250 PC Mate

I have the feeling my aoc g2460VQ6 is the problem. I also cant find any warnings or critical logs.

Thank you!
