Question on Computer Virus and Energy Dampeners

[Alneyan]

On the topic of Energy Dampeners: those cannot be stopped by anything (except destruction of the component or lack of supplies), unlike the Psychic equivalent, so they will work against Master Computers.

[Enigma]

OK I did up a sample design with computer virus against a ship with a Master Computer. In the first round it destroyed the Master Computer, but the enemy ship still fought pretty effectively. It did not have an auxilliary bridge. What is the effect on combat of losing the Master Computer?
