Hi Tonny, thanks for quick response!
First I did was as you said disabled
Toshiba PC Health Monitor. Well it didn't worked for me.
Then I uninstaled almost every Toshiba utililty (+except Value Added Package, Web Camera, HDD/SDD Alert+).
The problem was in
Rapid Storage Technology.
With that gone..
problem is solved, no more clicks.
Thank you anyway, you gave me a great clue what to do!
