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

Update (07/15/2019)
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?
Es esta una buena pregunta?

The error you got in AHT: 4MOT / 4 / 4000003: HDD-1361

Don't worry about the EMI foam on the HDD in the 2011 series the sensor is built into the drive. Which can be an issue if you replace the HDD with a new HDD or SSD. You'll need this sensor cable OWC In-line sensor of you do alter the drive.
As for your new error 4SNS / 1 / C0000008: TS2p -- 124
Verify that the Bluetooth/ camera/sensor cable is securely connected to the top of the logic board. Review connection guide below

Yeah I did notice that there was no wire in that connection while closing it up, maybe it got trapped under the board, I'll just find it later after I'm done with installing the OS

@danj got OSX running with hdd connected externally eveeything is OK including GPU (fan still spinning like crazy tho), HDD doesn't work internally so I'm buying a new SATA cable and will need to remove the logic board again as well as find the camera cable and attach it

Huge props to @danj for being patient and helping me fix this issue, the system is completely working now without any issues, GPU works fine as well as HDD, HDD fan and the rest.
