Summary

Hi all,
Desperately looking for a solution for a crash bug I’m getting with UEFN. On task manager it will show random GPU spikes to 100% or near and cause my pc to crash or reboot without any error message. Sometimes the spikes are slightly smaller which is how I’ve been able to notice them without crashing. Sometimes even while tabbed out of a project just idling, I will crash even though not on UE. Anything else on my computer runs smoothly and never crashes and this issue only ever occurs if I have UEFN open. I have a (BRAND NEW) INNO3D NVIDIA GeForce RTX 3060Ti.

The screen goes completely black but audio lasts for about another 10 seconds before that goes too, sometimes the PC will reboot itself and sometime I have to do it manually. I lose all progress when this happens, sometimes it happens within 5 minutes of activity and sometimes an hour, but never while loading up the editor. My thoughts are there must be a specific graphic or lighting that is causing this but my limited experience with computers makes this a bit difficult for me to solve on my own. My entire PC is brand new and only got it about 6 days ago and have been trying to fix this since, so for me its unlikely that its an issue with the GPU but please let me know if you think otherwise.

Any help or advice would be greatly appreciated, really desperate to get this fixed! :confused:
Let me know if you have any questions, thank you for reading :slight_smile:
