No sound is coming out of my speakers what so ever.   i unplugged em, Plugged 'em back it.      Restarted my PC a few times.   Checked out all my sound propertys, settings. etc
When i try and play a song on KaZaA or other music program 
 it says something like "you sound card is currently in use, please terminate the program using you sound or cancel"      Not in them exact words...
What's Wrong? 

   it's not my speakers cause the comps saying it also...   
I never ever had a problem with this comp, very good to me 

 But this one has me lost...please help, suggestions
I was cleaning around the computer- i picked the Computer (HardDrive,,,not monitor) and set it back down nicely.     Could the chip came loose? i doubt it but anything is possible.      i clean in the  comp  once a mounth w/ compressed air & Vaccum  to remove all unwanted crap.....maybe i will clean it & check it out today-   where is it located?
I'm still sick, 

 and been doing this " 

 " all night...so looks like i have some time to fix this thing  
 
 
   
         
thanks
mike
