FPS Drops suddenly and back to normal but only in some games and in some cases

[Nohmis]

Hello, I have quite strange problem about FPS Drop's, my PC is asus x555LN, the problem is different. It happends on different games, Starting with Counter Strike Global offensive what is quite different than comparing to others. So to begin with when im playing CSGO competetive after some time ( about 10-15 ) minutes my FPS drops from about 200 to like 20 for about 30seconds maybe less maybe more, then for like minute or two its decent FPS but then it happens over and over again this problem. Then when it comes to all other games I play no matter what it is I get this casual FPS drop from like 150 to 1 fps for 1 second its normal like my screen Freezes, sometimes this happends on CSGO as well but more it goes with the 1st problem I have mentioned. Anyone could help me with that?

May be thermal throttling, what kind of temps are you running with your CPU and gpu?

My tempretures were really high above 80 when playing CSGO, and when I bought cooling pad it did not helped at all it is still the same. But I think this has connection with another problem that im facing and it is when I want to shut down my computer I press it and then it comes with black screen but it doesn't shut down as it should, everything is still working just black screen, maybe it has something connected with FPS drops as well?

80C is very high. Maybe your cooling fan isn't working properly.
