I have attached a link to the maintenance and service guide for your laptop.

The only suggestion I can give is that you will need to update the bios to F.49 if that is compatible. It is a fix on HP Envy models for locking up.. However if that is not a viable option you may have to re-install the O/S as the windows system will be configured for the core 2 duo so will not recognise the quad. When you do a clean install it should install the correct settings. I have found this on other models when trying to change processors. The manufacturers do something which prohibits upgrades to processors etc. They would rather sell you a faster PC. My cynical gene showing there.

Hope that helps you somehow to resolve your problem.
