Weekend headache with the PC

[Sima01]

Hello guys,

Today i encountered an issue that i just can't resolve or atleast, confirm until the working day because I have no spare parts, I just want to see if im thinking the same way as you guys do.
So today i transfered my PC to another city where I got work and all fun and games it all went great I played some games, everything worked perfectly, BUT i wanted to move the PC and it went off, but not off in terms of all lights and fans out, just GPU lights. And after restart it started working again, but the issue is when i started to investigate, it never came back on, in the video below I recorded how it goes, i resetead the CPU, GPU, RAM checked, PSU checked. Cables checked, everything is great. I turn it on and after 15 seconds it turns down and boots again, no display, monitor recognizes it as a signal but doesn't show picture, GPU spins the fans but no LED as it should power on. And it seems like its working just fine, after its "ON" with no output, i can't turn it off by long press of the power button. 

GPU-MOBO-CPU-PSU-RAM are under warranty, I just want to figure out a way to find out if its the GPU as i suppose it is, or is it the MOBO, not going to lie to you, if its the gpu, i might send this 3060 TI to repair under warranty and buy a new one like 4070 with explanation of long repair time.

BTW i know the Arctic logo is upside down, and the fans are on the wrong sides because of the sound pads etc. Im too angry to care right now, wanted to play all weekend

It happened to me once and I had to wait about 15 minutes.

sadly, thats the one thing i didn't try, ye its quite new, maybe a year old, built it then. The issue is i moved today and i am improvising with the tools, maybe if i get some proper screwdrivers tomorrow on work and i can diagnose it there. But ye i will remove the CMOS battery now or jump the CMOS reset.

UPDATE: I removed battery and let it try to power on, the PC iteslef did something, GPU light came on, it restarded a bit, a bit too much but it started, it works like new, BUT THE main issue is, what causes it to have that issues is still not resolved. I moved it it stopped working, i jumpped clear CMOS now it works. It makes no sense, it has werid restarts before fully turning on but when ON it works like a beast

I think this is the mobo is the issue, os there is some kind of contact issue, im really not sure anymore.

It works like before, im fully confused, never seen an issue like this, like the mobo got sick or something, some weird contact issue that im not aware of... tried slapping the pc, opening and slamming the tempered glass to replicate the issue, it still works, magical...
