GPU keeps randomly crashing

Going out of my mind with this, got a brand new PC 10 months ago, had it for 4 weeks and the GPU keeps failing when plaing games, it cuts out and my screen goes blank like its not recieving an input any more and the fans whir at high speed, the only way I can fix it is to do a hard reset. I've tried 5 different GPUs in this system, it's been sent back twice and they've replaced every part of it and they still can't tell me why it is happening. The most recent thing I did was a clean install of Win 11 Pro using default settings, I didn't carry anything over. I installed MusicBee, VLC, Firefox and Steam, haven't changed any other settings and it's still happening, my current setup is as barebones as it gets, all DISM and sfc tests come back as normal. In the event viewer I get the following -

Audit events have been dropped by the transport. 0 Event ID 1101

I've tried everything I can think of here, I'm going mad. Is anyone able to help with this, please?
