OK heres what I got. HP m8000n. Yes I did not build my own I bought a family computer so my wife would not bury me in the yard. It came with 2 gig with 2 extra slots. I put in a 7600gs vid card(it only came with onboard one). Has AMD Athlon 64x2 dual core 5200+. 32 bit vista.

I am just on this side of stupid when it comes to computers so Can you change from 32 to 64??? Is that the windows program or is it in the motherboard??

Is there a sit to check what motherboard you have. I am assuming the motherboard is the telltell for how much you can upgrade.

With this system will getting more ram help or will I even notice?
