I have problem we my cd is shuf

select play mode on remote and change

It sounds like you have the cd on random or shuffle. Look to see if you have a button marked rdm or shuf or some variation of that. If so, try pressing that button to see if random/shuffle turns off.

yes external burners will hookup through a USB port and are plug and play any neeeded software can be downloaded from the suport site of the product manufacturer

That's short for "shuffle". In shuffle play, the player randomly picks a track from the CD to play, so you don't know which one is coming up next. On some Sony models with multiple-CD players, shuffling also randomly picks one of the discs as well as a random track. I don't know if yours is one of them, though.

There's a control under PLAY MODE that selects random play labeled "1 DISC SHUF". Normal play would be "ALBM". Read the manual.

Press the "suf/rep" button for 2 seconds until frequency appears, press Disc + or Disc - to change frequency, press shuf/rep for two seconds to save/exit.

there is usually a random button on most radios. it should be marked either rdm or shuf. not knowing what radio you have, makes it rather hard to say. you would get a much better response if you supply more information, such as what brand and model the radio is, or at least what kind of car it is in.

What do you mean by not ANY CD? Does it mean that you can play some CDs while others can't? If it can't play any CD at all, it might be that the sensor for the CD tray is not working. It is not recommended to change the sensor yourself. Since you have contacted the service department of the player, give them 2-3 working days to get back to you.

Try the compaq site.
if not did you have any restore cd's that came with it.
it may contain drivers

pls change the cd or first of all uninstall the privious nero and then upgrade the os then again reinstall nero .
