Question Pc restarts

[sindhu84]

Hello
I have recently build my system 15 days ago.
Specs are
Core i9 9900k
Noctua d15s
Msi z390 ace
32 gb Corsair dominator xmp on
Msi gtx 1080 gaming x
Evga t2 850
Everything was working fine.After yesterday update of windows 10, whenever i run any game my pc gets restarted even a stress program like Cinebench is launched. If i do simple internet browsing pc runs fine.
Need help
Thankx.
