how to run (GTA IV) in windows 7 with 3.00 GHz processor and 1.00 GB memory and 64 MB graphic
sorry mate but you barely hit the requirements to run win7
let alone play any games at all
that gpu might as well be binned as you get better graphics built into modern cpu's e.g. intel hd 4000/3000 graphics
and i believe a lot of onboard graphics built into motherboards are better as well.
