Raz,
That is the model number of your monitor not your desktop. I would need the model number of your desktop. Have you any knowledge of how to overclock? I do not recommend overclocking on stock cooling especially if this is your main computer. Although i dont know for sure if HP locked all overclocking features from the user i am going to assume they did. These manufacturers do this to keep people from damaging the system. Please look on your Tower for the model of the computer, than i can try to confirm if you can overclock or not.
