My pc shuts down randomly but only if i play or start games it sometimes happens every time i start a game sometimes it doest happen at all for months.
My pc
1070ti
i5 6600k
8gb ram
2tb hdd 128 gb ssd
750 w 80+bronze psu
 
Solution
Most common cause is PSU issue, what make and model is it. 750w on its own is meaningless.

Next most common cause is probably heat. What are your cpu and gpu temperatures when gaming?
