Hi and welcome Hyperlost,
Was there previously any security software installed?
If yes, please try the corresponding clean-up/removal tool if it is listed in the link below.

thank you and sorry for silly question. :-TU

Can you check the Tasks logs to see if at that moment the cache builder/cache cleaner process was running? That will take up quite a few CPU cycles and will not throtle back when the system is no longer idle.
