Computer shuts down after gaming for a long period of time

[DrDukeNukem20]

My Pc: i5, msi motherboard, gtx 760, ........
My whole computer just shut down after playing GTA V for a long time period. This never happened before. Is it because the cpu got to hot?( I am using a cpu fan) What should I do to not have it happen again. ( If you suggest any thing for my pc, can you send me a link)

Thank you

Have you checked what temps you are getting for the CPU and GPU when gaming? And when idle?

What about the loads that the CPU and GPU are at also?

Have you looked up to see if there is a glitch that can happen when playing that game, causing the issue?

When the computer turned back on I check the temp of the cpu it was around 200 F(higher) right now just writing you back its around 120 F. I am using CPUID
