Sony Vaio upgrade

Hello,
Can my Sony Vaio Laptop Model PCG-7112L that currently has 2MB of RAM be upgraded to 3MB of RAM? Please help. My daughter has to run a software program at school that requires 3MB of RAM to run and I need to to decide if I need to buy her a new computer or upgrade the one she has. Mike in Houston

  1. It appears the computer will hold 4gb of ram. 3gb will be see by a 32 bit os.
    If you install a 64 bit os the USB drivers won't work. See below:

    What program will she be using?
    My guess she could probally use a processor upgrade as well!
