My laptop recently stopped working for no reason.I managed to fix it by using a recovery disk, I lost all my files but it works perfectly fine. But windows media player won't let me play any music files as it tells me "A number of queued files cannot be played. To find information about the problem, click the Now Playing tab, and then click the icon next to each file in the List pane" For some reason the sound on it won't work or play (My friend suggested it was the sound card.) Any suggestions how to sort this problem out? Many thanks.
