First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty. Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.
Then go to control panel,system ,hardware ,device manager option There if u find any question mark or exclamation mark in yellow Color that means sound drivers are not installed properly please reinstall sound drivers properly
If no question mark or exclamation mark then check the cable connections of the speaker to the machine
In control panel , select sound audio devices open it there u have volume,sounds,audio,voice,hardware options
1)See whether it is mute 2)In audio option select default audio device and recording device should be same
this should solve u r problem .if it is not solved please let me know u r problem briefly
or else put the model number and brand name followed by drivers search in ww.google.com
First make sure you don't just have it muted... seems simple but its happens. Open the volume controls and make sure the mute is not checked. If that doesn't work, try removing the sound card drivers and reinstalling them after a reboot. If both the speakers and the headphones don't work its most likely the drivers, however there is a chance the sound card has gone bad as well. . . Try the driver reinstall and if that doesn't work you will need to have it serviced.
try to find the volume in your task bar, maybe was set to mute. if not see the volume. go to control panel double click the " audio and sound device" uncheck the mute "box" , same probelm occur. do this, Install the correct audio driver, maybe have error on it, Find the CD/DVD utilities of your computer and the install the audio driver., if don,t have CD/DVD utilities tell me the Audio card model number or if the audio is builtin to motherboard tell me the motherboard for me to search the driver for you to download.
