Question: there is no sound what so ever  on my pc what can i do to check what is wrong ? i have no idea? 

Answer: There could be three possible reasons why your sound card no longer works.  Assuming you had sound before, it could be the sound card itself, the speakers or the driver that makes the sound card work.  \nThe speakers are the easiest to get off the list.  Get a pair of headphones and plug them in "input" jack on your sound card.  If you hear sound, then it's your speakers, check to insure they are turned on and the wire isn't broken.\nNext is the driver.  If you are running Windows XP you can go to the device manager and see if windows thinks the sound card is working, if not use the windows hardware wizard to see if windows can sort things out and that also include the updated driver.\nLast is your sound card might be dead.  Well first check to insure it is still seated into the mother board if you have a plug in sound card, but you might have a sound card built into your motherboard and with that, you might need to disable your built in card and get a replacement plug in card.
