I am developping an OpenGL graphics program in Arch Linux. Everything was working fine, except I recently attempted to render the Sponza scene.
The program launches and runs fine, however my GPU starts making a screeching noise (I imagine it's the fans turning too quickly) and after about a minute the entire system crashes and reboots.
Checking VRAM shows that there is still at leas 4GB of VRAM available when the program crashes, so I don't think this is a running out of memory problem.
The other potential problem I can think off is my power supply running out of power, however I have a 750B evga power supply and my GPU is only consuming 119W out of 200W at the time of the crash (inspected with nvidia-smi).
Given that the system reboots when the error happens I am not sure which log to inspect to determine the caus eof the error.
