Well some times when i open up steam to play a game its not installed and i know i have downloaded and installed it before, so i go into settings/downloads/steam libary folders, i find the harddrive that it installed the steam game to that i wanted to play and then select it press ok and then it is installed??? I'm not to bothered by this but i want to know why is it steam or my computer. fyi i have 3 hard drives each 180gb (i got them for free from my uncle when i was building my computer i was on a budget so im not complaining)
