[SOLVED] PC suddenly in boot loop ?

[RedScope]

So I was playing a game on my PC, and accidentally pulled it with my leg and it kind of tilted a bit to the right side before falling back down on its own to the 4 stands. It wasnt a major pull nor was the impact big but the pc froze. So I turned off power to the psu on its button, and turned it back on and booted again, but I got no image on my monitor.

This has happened before and I fixed it by switching the display cables used, so I unplugged the DP cable and tried again but replugging after boot to no result. Then I tried plugging an hdmi as well and swapping input after but to the same result. I then booted with only hdmi connected and then I somehow also got no signal on my keyboard or mouse. Not just that but it would boot, spin fans intensely for a while and turn off before rebooting on its own and repeating.

I've;
unplugged hdmi
plugged dp
unplugged both
reset the gpu
reset ram
unplugged and plugged both motherboard and cpu power connectors
held the power button down after unplugging power for a bit
and after all this, the same boot loop, even when only connecting keyboard and hdmi or DP
and I still don't get signal on my keyboard.

I also looked at the components to see if there was any crack (which would be weird given I barely pulled the case) or cable that might have fallen on something that could be shorting, but I genuinely can't find anything weird.

I can't understand how I went from no picture to no boot simply for swapping/adding a display cable. Help and tips appreciated.

Cpu: pentium g4600
Mobo: gigabyte b250m-d3h
Gpu: gigabyte gtx 1050
Ram: 4x2gb 2400mhz
Psu: corsair cx650m (from 2016 I think)

Does your system complete POST and go to OS GUI if you remove the discrete GPU from your build? Try and breadboard the system with the bare minimum, meaning only one stick of ram, the processor + iGPU and motherboard hooked up to the PSU out of the case.

Very likely that you either damaged the motherboard due to the man made fall or that it's shorted out a component during said fall.

This has happened before
If the PC falls as stated prior, then this isn't healthy for your PC.

I meant it has happened before that after crashing or something it wouldn't display anything unless I swapped display cables around a bit.
I've breadboarded it and deep cleaned everything, and suddenly it wouldn't even turn on so I paper clipped the psu which worked and I put the mobo in cardboard and it started so I think something in the case is now also shorting it. Oh well. As for the boot issue, I narrowed it to ram slot 3, all sticks worked elsewhere and booted properly, I just don't see any physical damage on either the slot or the back of it so I am kinda unsure what to do, if there is anything that I can do at all

Actually I was wrong, after troubleshooting some more the real issue is using quad channel. I can boot fine on single, dual or triple channel memory but if populate all slots it will loop. I'm clueless rn lol.

Ty Jeffrey but I got it working now, I turned on memory enhanced stability in bios and disabled fast boot, after I booted with 3 sticks, and tried booting with 4 after doing that, and finally it properly booted with everything connected.
