Can't figure out if GPU is dead or HDD on iMac 2013
I can't boot into MacOS, won't go past Apple with the loading wheel. Recovery mode works for a while and crashes, graphics are just a bit slow and glitchy at times. I think the HDD is corrupted as verbose startup says The Volume Macintosh HDD could not be verified properly. I can sometimes boot into ubuntu if it does not go to a black/gray screen.
If I boot into ubuntu and try to access my HDD it crashes, if not it eventually crashes anyway. I get BSODs both blue and black.
This Mac's GPU was repaired (reballed I think) a few years ago after it stopped working.
Is the GPU dead or the HDD? I can provide pictures of whats going on as well.
Tried PRAM, SMC resets already

Managed to get it on internet recovery
However no drive shows up, I'll try to reconnect the cables, also whats up with the fan, its still spinning like crazy
I think I figured it out from here forgot to transfer the hard drive emi foam
I forgot to replace that EMI foam and I dont have it, is there another way to seat it temporarily using like tissue paper or something?
+ ran AHT and got this error, looks like ODD fan/sensor?
