All I want to achieve is more processing power and RAM.
Windows 7 ultimate 32-bit
CPU: Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz (2 CPUs), ~2.2GHz
GFX: Intel(R) 82945G Express Chipset Family
364 GB Hard Drive
I don't even know what type of RAM I have, but I'm certain it's not DDR2 or 3. I'd like to get DDR3, but what compatibility issues would I have and what else would I have to upgrade for that to work?
