4 cores, 8 threads. As others are pointing out, this could be thermal. Clean the fan, consider replacing the power supply, consider removing the heatsink and cleaning it then re-applying thermal paste. If the problem recurs and it isn't thermal, you can replace the CPU. i7-5775C or another i7-4790S will go for about $200; a used i7-4770K will be nearly unnoticeably faster for about $180. -dsr-
