I finally find a cure !
My problem was a confilct between my audio card driver (Xonar DGX Audio center) and corsair Icue ... The blame is for asus because after installing an alternative driver find here (http://maxedtech.com/asus-xonar-unified-drivers/) and not selecting the installation of the audio center (the second option on the installer) the problem is not here anymore !!!!
I have this problem since 2 years ! I was blaming corsair for that but no no no, the blame is on ASUS !
PS : i was having the same memory issue on shutdown with origin, it dissapear too ! So the blame is REALLY on ASUS and not Corsair , for sure :)
PS2: The driver also fix a problem of BSOD when i was waking up my PC after a sleep mode ...
