ok . when i want to install a new game or whatever, i have to do it manually. i use to be able to just stick the cd in the pc and it would start up, however i have to go to "start" "run" and start it myself , witch isnt that big of a deal, but my pc use to do this , without me haveing to. did i shut something off , and if so how can i turn it back on so when i put a new cd in , it starts on its own?
