Hi I have an Hp Pavilion a4302f and the hard disk drive is supposed to be 500 Gbs and the OS says "90.4 GB free of 139 GB. This pc has been given to me by my aunt and she formatted it I think. I will upgrade this computer for gaming but before that i need to get this problem fixed! Please help! P.S I really don't want to have to re-format it because i already have games on it that took a really took a long time to download
