Playing music freezes PC

Hi to all, I downloaded win 7 4 days ago, for now it's working fine but having problems with my music files, I did a back up of my files, have restored all my files but when I try to do the music files it freezes I noticed that my processor dual core 2 runs at 100%, when I cancel the operation processor goes down to about 2to 5%, this happens also when I open window media player, I just downloaded Itunes that I use for my Ipod, I try to open Itunes and nothing happens, any advise on what could be the problem??

What do you use to play the music files, just Windows Media Player? Do any other music players do this too (like VLC Player).

Also, which process is it that remains at 100%?

yes I did until just a while ago when I downloaded Itunes, it seems it's working fine it is converting my music files as I write this reply havent use it yet, about the processor anytime I use the windows media player the prossesor will shoot to 100% of usage as per cpu meter with no other program working, besides I have tried to restore my music files and everytime I try the program freezes.

hello, i just recently bought an hp pavilion laptop with windows 7 on it. ever since I have bought the computer I have been having problems, and I believe the culprit is windows 7. Whenever I visit music websites (pandora, grooveshark) or youtube the internet freezes, and then I have to restart the explorer window. I am a college student and am wondering if the firewalls or virus protection (norton antivirus) that they have installed are restrcting my acsess. No one else has expereinces problems, yet none of them have windows 7. Therefore before I go and return this computer and exchange it for one that works (as I am not very computer literate) and really only want a reliable computer is there anything that can be done? Thank you much for your time!

I dont think you will find an answer to your petition here, I have been waiting for a reply to my inquiry since july. I f Microsoft dont fix the problem I will reinstall win vista, for me personally the the win 7 is no good.

hiii!
im really happy 'cause i've fixed the problem or at least it work for me
just go to google, write windows and enter to microsoft's web...
then, go to helps and procedements - windows 7 ... in top solution you will find NO SOUND OR SOUND PROBLEMS click and do all what they told you to do.
open the fixer programs and after all of that you might play music without problem
i hope that its not too late for you
au revoir

pd: i speak spanish but i do my best and i hope you can uderstand me

Always verify you have the latest sound drivers for your equipment

And you might try Microsoft Fix-it, simply choose the one for sound problems.

Yeah... i was trying to said so... but i didnt remember the name of the program I'd downloaded from microsoft web

hey bro
in my last pot i said I'd found the solution and it really worked for 2 days
today it has started again and now its worst :'(
i hope somebody has the answer and share it with us :'(

Make and model of your PC? What windows OS do you have, 32 or 64-bit?
What anti-virus software are you using?
Do any other applications slow down or only your music? Is the music on your hard drive as an mp3? or is it on a CD? or on a flash drive? or streaming from the web?
