No signal out

[rubynormal70527]

I was playing apex legends and all of sudden my display turned off and I started hear glitched audio from the game with no output. now after hours and hours of troubleshooting I haven't gotten any solution and post of the existing solution don't seem to help 

Specs 
Ryzen 5 3600
Rtx 3060 by inno3d
550 gigabyte 80+ bronze 
2 sticks of ram 8*8 from gskill 
1 tb SATA SSD and 1tb hdd

I built this PC myself couple weeks ago 
I also happen to have an another system 
So I was able to swap some stuff around see if it posts eventually I got to the graphics card which got the system back up running immediately so I put my rtx 3060 in the other system and to my surprise it posted there. upon switching it back to it original config my main rig didn't post again. Repeating all the steps again now this graphics card wouldn't post on my other rig either and now it has no video out on any PC I changed multiple cables tried HDMI tried dp unfortunately now nothing works 
I think I might have to send it back and hopefully they take it 

Specs for the other PC 
I5 8400 
GTX 1060
Cooler master 450 80+ bronze
