Sounds Gone

Hi
so i went turned on my computer as normal, and then i realised that the sound was gone, so i unplugged my speakers and put in my earphones, but it still didnt work, it says that no audio devices are connected, So if you know how to help please tell me its driving me nuts!!

My computer specs (if it makes a difference are)
Windows Vista
Realtek HD audio
4gb ram

Thanks

 

Have you tried to re-install the sound drivers? If not, here's the newest ones. http://www.majorgeeks.com/Realtek_High_Definition_Audio_for_2KXP03_d4902.html Let me know how it goes!! Try this also, right click My Computer>properties>hardware> device manager. Do you see any 'yellow' question marks or exclamination marks?

 

If Stubby's suggestion doesn't work please run and post an everest report along with your computer make and model.
