Sound i have install window XP SP2, my sound doesn't come, when i try to play something it say "Windows Media Player cannot play the file because there is a problem with your sound device. There may not be a sound device installed on your computer, it may be in use by another program, or it may not be functioning properly." this that message come ups. i try everything on control Parnell. i am not sure what wrong with.

First off download (pcwizard) and install this program searches and finds the drivers needed for your computer go to the sound driver found note name and number write them down
EG cmedia 2341
go to search engine type in (cmedia 2341 drivers) put your own needed driver where I have cmedia etc and search for them download uninstall any sound driver installed reboot when rebooted install your sound drivers.
Sorry cannot be more specific as I do not know what your sound card is

Plz detail UR System Specs (At least Motherboard) as well as Sound Driver Name & Version.
