my name is amos. I just brought a referbished Dell Optiplex GX280 with windows XP.
The reason for that is that I'm doing a home study for the compTIA A+ NET+ certification.
And I want to know if I can upgrade my cpu from a 32bit to a 64bit or what can I do to upgrade my system to be able to run 32/64 without buying a whole new system???
