I have a CDROM attached to my P III computer. CD ROM is working fine with all CDs except with few of my setup CD.. When i double click my setup file, it is not responding.. all other files are opening. The same setup file is working with other CDROM in a different machine.. when i connect another CDROM with this my machine then also it is not working. Is it a problem with my OS.. i reinstalled windows with out formatting, still the problem is there... Pls help me out..
