For some time, the render was not bad, but then the system hung, after which it was time for the blue screen. After the reboot, it turned out that the video card that was used for the denoiser was burnt.
I don't think that any software can burn graphic cards. It can happen if it has near to end-of-life or weak against the stress of high calculations.
