If it's from the Positivo brand, no way, I'm from Brazil too and I know it's all glued to the board, with luck maybe just put more memory.
From what I've researched, it's a very old cpu, even if he can upgrade it, still won't be enough to run this game decently because the board should not accept better cpus, like an I3 or etc.
Well...
Looking even more, i can see it is a dual core no hyper-threading (means a total of 2 cores only) Pentium with only 32-bit support.
Too be nice...
I Strongly recommend to upgrade your pc.
(most people today would want 8gb or more in total ram and 64-bit os.
(the last one is easier to get then you think today, 64 bit os i mean).
A tip from me: Check what you can find used. You can usually find pretty good parts (even if it is not the latest and best).
