is your computer had a memoryddr of 512? or lower?
I'll advice with this but don't know if it will work.

on the right side there are some application image. close the ones you can close then try to plug your mp3 player.
WMP is a windos codec. try to download registry mechanic to fix your problems. and it will make your computer faster. ( if it will work on your pc but have a try).
if you can't find any registry mechanic.
I'll send you the installation though.
