PC Reboots playing csgo

[svenska7]

Hey guys, so as you can see on the title, my pc reboots when I try to play csgo. It happends when I get to the server. My specs are:
Intel core i5 3570k 3.4
Asrock itx z77e
Gtx 960 4gb
Samsung ssd 240 gb
Corsair VS650

Already did a format, played another games and everything works fine. No problems on boot, no overheating, nothing. I just can't play csgo.

Thank you, and sorry for my bad english lol

Did you try reinstalling CSGO? If you have you may need to reinstall windows if it has been awhile since your last install. Though I might try running DDU first in safe mode and see if that helps.
