Hi. Recently I had trouble with system overheating while playing (pc dvd) video games due to dvd drive working excessively. So I decided to make an .iso file and not use dvd/drive at all. I saved .ISO, used winrar to extract the files and managed to install it but after clicking "game icon" to start playing it says "no disc inserted"? I don't get it, it installed properly, shouldn't it be able to recognise all the files and everything? Any ideas? What am I doing wrong? Thanks.
