Increasing RAM
I have a Packard Bell desktop PC which, if possible, I'd like to upgrade.
The processor is Intel Core i3 CPU, 540 @ 3.07ghz, installed memory (RAM) 3GB, 64bit operating system.
My question is can I upgrade the RAM to say 1 terabyte without having to upgrade anything else, and if so, how do I establish what will fit the PC ?
