Title, nothing much to explain, other than that I think that this is a new problem the pc is new, I got it in the 9th of July.

I have translated the other lines.
EDIT:
it is not only in youtube, firefox, its in Watch Dogs, GTA V, in watch dogs and gta v it is between 90-100 percents since this problem occoured.

Then I am not sure what is causing it. Some program is using the cpu a lot when playing games but I don't know what that program is. This assumes you have no viruses on your machine and have all the win and driver updates.

Norton 360 is doing a quick scan in my PC and a full system scan every so often, so there are no viruses. Drivers are all installed via MSI Liveupdate 6 and windows updates, I assume?

I don't know about msi liveupdate6 but windows update should install all the updates automatically by default.

You should ditch Norton and get Bitdefender or Kaspersky. I've had bad experiences with Norton, so yeah.

Thanks for the suggestions, but I am going to stay with Norton, I am happy with it and it gives me all what I need, including 24/7 chat support.
I am even gonna renew it, I have never had any bad experience with Symantec.

Ah Norton, that'll eat CPU, never liked Norton myself. Is there a "game mode" option maybe?

 

[Itay080]

Well, I just took the PC to the store so they can check it and they said that as long as I dont have perfomabce issues and its not lagging or something like that, then its ok and it happenes because in GTA V for example to give me the best perfomance it LIMITS the game to use all of the CPU, and as long as I have warranty and no perfomance issues, I have nothing to worry about.
And teknobug, Norton automatclly goes into silent mode when launching a game.
Thanks everyone!
