check to see if they are plugged contained by. one time i was adjectives pissed off bring mine weren't working, but it turned out that I had moved the monitor and it cause the speakers to be unplugged (stupid cord is too short).
Make sure that the volume on the speakers, in window, and the application your are using to listen to are all up.
Make sure the connections are proper and the cvolume is not muted. Try connecting a headset to check the nouns. If that works then something is wrong near your speaker. Otherwise your sound card is screwed up and desires replacement, If it an onboard sound card later you need to replace the motherboard or receive a new affix on sound card.
Dear friend!

Check by replacing the speakers. After that u can check the volume within ur player as well contained by ur system volume icon.It shoul not be mute. If u enjoy gone through all the things, next u would have to install drive for ur nouns card. I am damsure this will work for u And u would be able to delight in music on ur pc.
