shutsdown PC after 15-20mins mining

[xbyte26]

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

why me ? :D more seriously ccminer and mtp doesn't cause cpu to overheat, cpu is usage is minimal around 0.1-0.2%

On another hand, gpu will overheat if not cooled properly. I would rather look through psu issues...

lol, I'm very sorry, that's not what I meant. Anyway, I tried T-Rex miner (MTP) and I encountered the same issue. I don't have PSU issues since I can mine ETH wihthout any trouble. Can you share what's the ideal OC settings for 1080ti 11gb + Pills? I think maybe my settings that shutsdown my PC.
