no sound coming from computer with any speakers/headphones?

away to fix that is its your sound driver it probly got corrupted or wasnt installed correctly go to control panel and go to device manger find your sound driver and right click it and hit update if theres no error message that should fix it if not uninstall it and go to your pc manufacter website and redownload and install your sound driver

Check the volume control on the computer and turn it up. Computers does not have enough power to drive some speakers, you'll need speakers with built in amplifier designed for computers. Individual speakers hooked up (like home theater speaker require more power to drive them than what your computer can supply) to the computer will not work.

Try using different hardware, if possible, i.e. other available speakers etc. If not then you should check for the driver itself. So many websites you could find your driver on or you could get it from a local vendor for a price. If nothing works, change your sound card, its not that expensive.
