processor: AMD Athlon 3000G (using stock fan)
GPU: 3 x GTX1080 Ti
(OG Pills)

When I mine FIRO using ccminer (GPU) for 15-20mins, my PC shutsdown and took a while to turn it on again. Before, I'm mining ETH but I didn't encounter any issue. I think my processor is overheated that's why it shutsdown and once it cools down I can turn on the PC again. Please help check.

Thanks
