Upgrade Processor Hp Pavilion

How do I upgrade my HP laptop to play the PC game “Bio-shock” and other current PC games like it?
( RE: How can I upgraded my HP Pavilion dv6000 32 bit operating system to a 64 bit with out getting a new laptop? )
if it has,
Model: HP Pavilion dv6000
Processor: Intel(R) Core(TM)2 CPU T5600 @ 1.83GHz
RAM: 2038 MB a little over 2GB
System type: 32 – bit Operating System
Either your hardware is 64 bit compatible or its not, there is no way to upgrade it to make it compatible.
BTW, 2038mb of ram is not “a little over 2gb” of ram, it is actually a little under 2gb. 1gb=1024mb. My guess is that you have a video card that steals ram from the system.
