Thank for your quick reply, I'll try to do that.
BTW, the PC is brand new (no BIOS update on the X9SRA motherboard) and containt 1 SSD and 1 HDD both SATA 3 if that info could help...
EDIT:
Already have the lastest drivers (at least I think so): Intel Corporation C602 chipset 4-Port SATA Storage Control Unit AND Intel Corporation C600/X79 series chipset 6-Port SATA AHCI Controller.
The BSOD error that I get is : DRIVER_IRQL_NOT_LESS_OR_EQUAL from iaStors.sys.
