Ya thats exactly what I mean. And I have tried all the options u listed, the first, when I went to device manager, There wasnt even a CD/DVD drive, n when there was I uninstalled it and re installed it still not result.
I have a laptop, not desktop, I also tired the other option , I couldnt find the upper n lower filters???
I was thinking maybe a computer format will solve the problem??
Thank u anyway
