An incorrect setting in the BIOS versions below 1.0.6 could cause a system to shut down during heavy processor usage. Under heavy load the processor's Turbo Boost will activate, generating a power spike that may result in an unexpected shutdown due to the before mentioned BIOS setting.

Also the system performance may drop as a result of this.
