Since you upgraded the computer, without upgrading Quindos, then yes your problem is that the 'old' version of Quindos6 is not compatible with the 'new' hardware. (And how could it be. Your version of Quindos6 was written back in 2003, before hyperthreading or dual core processors were offered as standard with our machines.)
Again, either update the version of Quindos6, or upgrade to Quindos7.
