My Sony CD-RW CRX216E used to be able to read games such as Rise of Nations, Age of Empires II etc. just fine, in fact I had them installed and uninstalled them cuz I was running out of space on my Hard Drive. So I wanted to reinstall Rise of Nations. Now I put the games in the drive and the drive whirrs and my explorer.exe crashes. I put the same games in my other Dell 4300 and the games read fine without error. Also, sometimes I will start up my computer and My Computer will not even show a (d drive at all. I have to restart the computer for the drive to show on my computer. Sometimes I put in games and it says that it is not the correct CD, but it is. Could this be a problem with the CD-RW reader going defective?
