I would like to recommend you that can you please mentioned what temperature you are getting on the BIOS for the hardware? Because it seems like surely there could be some problem with the overheating only. As you have mentioned like it might be possible like the GPU must be overheating but alongside it would be better to test the whole machine for finding out the exact threat. By the way can you please mentioned the specification of you machine so that i could understand whether is some problem because of any mismatched hardware.
