It could be overheating. How old is the PC & when was the last time you clean it?

Most likely it is overheating then. Download some temperature monitoring software like core temp to monitor the CPU temperature. If you can, reseat the CPU cooler ( apply new thermal paste - watch how to videos ) and clean the heatsink.
