Weird Problem: all sounds will play except MP3's

[jamesey]

My friend has a computer, just built for her.

AMD 900
128 megs of PC 133
ATI 8 Meg Vcard
SBLive Value

Every sound except 1 works on her computer i.e, AOL noises, ICQ uh-oh's, error beeps, windows start-up, the "click" when web pages change.

MP3's will not play.
We tried using windows mplayer 2, winamp, & MMJ, and the computer freezes each time. We've tried various MP3's. none work.

any ideas?
I just installed all the latest drivers for the SBLive, mobo, vid card.

What is the OS? What resources is the sound card sharing? Are you playing the MP3 from CD or the HD?

Go to your audio codecs under sound video and game controllers in the devices manager and see what it says about mp3 codec. Also try the newest media player, I'm not sure what mplayer 2 is) try 7.1 it should work.
