hello there. i bought a new philips laptop with vista home prem. it plays
some of my cds but not all. the cds that i am playing are all originals and
they are not stratched or damaged. when i play the cds in another laptop with
windows xp they play as normal.
in my laptop the system will not reconise that there is even a cd in the
drive and when i go to my computer and click on the e drive ..nothing
happens. it acts like there is no cd there when there is.
in my friends laptop when you put in the same cd it plays as normal.
can you help me. why does it play some and not the others. is it a software
problem?? can u make it work? I dont think that it should be doing this.
Thanks
