My friend just upgraded his computer to Win XP Pro. But there is some problems. He used to have a game installed in the computer, but now when he plays the game, the game is very slow (the game is a web-based .... RPG game...). Later, he found out that his RAM is 1 time smaller than the ram that he used to have. Before he upgraded to XP pro, he used Win 98 and had about 256 RAM, But now he only had about 120 RAM.
Is there any solution? Or is there any way to increase the RAM?
