Maybe this has something to do with ur CPU..
Its so old, that i would not bet it could run any of the games that u have stated at 1/2 a frame.
This really dosent make any sence. You CPU is not only very old, but its a Sempron, wich is a very bad CPU alltogether..
And i think u mean 1GB of RAM.
Even though my suggestions weren't the right ones to solve the problem, at least I actually suggested something. All you ever did was say that his computer wasn't good enough to play the game, in your usual fasion.
Usuall Fashion? umm, do i know u?
