I am not able to hear the sound from my PC speakers

I don't know which windows you have but there kind of alike when it comes to test the sound card. In the control panel, open the sound applet and you can see if the sound card shows and then test it.
If you can hear a sound coming from the speakers then test the earphones. If OK then run anti-virus.

Sounds like the automatic circuit protection. Check to make sure you have good speakers and NO shorted wires to them. Too many spearkers conected to the outputs will cause the same problem.

did you check to see if the speakers are muted, Go to the little speaker icon in the tray (toward the right), left click on it and open the "mixer", you should be able to see if the sound is muted there. If it isn't muted, try plugging in some earphone and play some music or something you know works on your computer. If you hear sound from the earphones, then you know your sound fuction is ok and that the problem may be the spearkers ( if this is a laptop, you could still have a spearer problem, but more difficult to fix) hope this helps.

Double check to see if the volume on your computer tower (if there's a knob for it) isn't muted, and make sure you haven't muted the sound in windows (see the speaker icon in the bottom right).

mcdevito75 here, You can try to go to Start, then control Board, then to speech, audio devises, and un-check the mute box and check the icon in tray box, the windows up-grade maybe muted your computers sound??.

I would suggest you test your speakers with another source of audio (eg. walk-man). Using cellphone radio intruption isn't a good test.

 

Then you can try to troubleshoot your sound card.

 

1) assuming your using windowsxp you should download the drivers from the manufacutrers website. (if you have a brand name computer eg. dell, sony etc.. it makes determining your sound card driver and download easier). If generic system you have to open your computer and locate the sound-card manufacturer. (NOTE: please use caution when opening computer and have to be grounded and in a secure surface with proper tools.

 

2) once you have downloaded the driver; right-click "My Computer" and choose manage. From the device manager 

 choose sound and remove the driver. Reboot your system and when it boots up it should detect your sound card;  from the location you have downloaded and save the files update the driver when it prompts you.

 

Hope this helps
