CPU and GPU go to 100% usage constantly

[a.kolozyan]

Hi guys.
I have a PC with
-i5 3570k
-gtx 660
-Corsair CX600

I have been playing games and once in like 5 minutes my CPU and GPU go to 100% and then they drop together( so no bottlenecking), that causes the game to stop like 5 seconds and then I can continue. This happens also when I use editing softwares, it feels like my cpu goes very fast to high percentages.
Maybe it has to do with the temperatures, but when gaming my gpu is 70 degrees and cpu 50 degrees.

Please help me and thank you in advance
