I want to upgrade my dieing processor to a 64 bit but i am not sure if my computer is compatible.
All OEM CPU's shipped on that unit are 64bit if your looking to upgrade these are the max Q6600 or Q6700. Q6600's you can pick off Ebay for around $15 while the Q6700 will run up to $40 as they are a little harder to find. If your using this machine for common tasks consider migrating the OS to Linux Lite or one of the other Linux Distros, it will be much faster overall in everything you do.
