Burning slow

[mav41]

I've had my computer for less than a year, everything works fine. the only problem is it takes longer to read and burn a disc, it has no problems recognizing a disc,it just takes a long time to read it and burn it. Another thing is, when playing music from a cd the music sounds kind of slow and crackly, it sounds as if the disc was dirty, but i already tried a lens cleaner.The problem came about when i was playing a mixed cd i have and i guess the disc was dirty or damaged and the player froze so i closed it, then i tried a different cd and that's when it started.The player works(windows media player) and I have no problem playing music that's saved on computer.

What are the rest of the specs of the HP?
Or make and model if you don't know the specs.
And what version of XP, Home or Pro?
And what service pack?
What happened before this started?

I'm not quite sure what you mean above, but I have the feeling you may now have a damaged drive.  Replacement may be the only solution.
