PC goes black and fans go crazy when playing overwatch

[Fireball_1]

ok so basically every time I find a game of overwatch as soon as it says "found game" (especially on comp games which really irritates me) it just shuts off and the fans go crazy, none of my cores are parked and I do not have anything over clocked
My specs :
2x8 G skill ripjaw ram
I5 6600k (not over clocked)
gigabyte gtx 1070 g1 gaming
seasonic s12II 620 bronze ss 620 gb
1 tb of wd blue hard drive
850 Evo 250 gb of sata 3 ssd
(Edit: If I bump into it it also goes crazy, same black screen same fans going ham but it doesn't shut off

Sounds like something could be overheating, are you monitoring your temps?

nope, how do I go about doing that

Download piriforms speccy, this program will allow you to monitor all of your system temps.

Close EVERYTHING, wait 10 minutes then open speccy. Now write down your CPU temp and your Graphics Card temp. And reply in this thread with your idle temps

Then keep speccy open and open up overwatch, and try to find a game (or do what makes your screen go black and fans speed up) and watch your temps as it goes black.

Post those temps in here as well
