Brand new PC, bought and pre-assembled minus storage and GPU which I installed myself.
GPU would work fine but then the fans would completely stop working after a minute or two, leaving a static image on the screen. Every other fan is spinning and lighting up. Switching the place of the m.2 and doing some rewiring seemed to fix the problem and I managed to install windows but I was bombared with error messages, managed to install one driver then reboot but then it crashed again and the same problems started appearing again. Currently unable to access windows installed, boot from a USB, or even stay in the bios before the GPU fans die. (Possibly irrelevant note: the case gives a tingling sensation when touched with 1 or 2 fingers but doesn't seem to do that when handled by 3 or more fingers).
The standard way to see if it’s a dead gpu issue is to put the card in a known good system and see if you can get it to boot. A reverse method is to put a different card in the system and see if it can be gotten to run.
