Need a little PC Help, PLEASE!

[Striper SniperX]

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
