This is not enough information to get focused troubleshooting. What have
you already tried? What changed between the time things worked and the
time they didn't? Some suggestions:
A. Look in Device Manager - is there a yellow exclamation mark next to
your sound hardware? If so, try updating the sound card drivers. Never
get drivers from Windows Update. Get them from:
1. The device mftr.'s website; OR
2. The motherboard mftr.'s website if hardware is onboard; OR
3. The OEM's website for your specific machine if you have an OEM
computer (HP, Dell, Sony, etc.).
Read the installation instructions on the website where you get the
drivers.
To find out what hardware is in your computer:
1. Read any documentation you got when you bought the computer.
2. If the computer is OEM, go to the OEM's website for your specific
model machine and look at the specs (you'll be there to get the drivers
anyway)
3. Download, install and run a free system inventory program like Belarc
Advisor. The older Aida32 is good for this, too.

If you have installed drivers from Windows Update, you can roll them
back:

B. If updating the drivers doesn't help, swap out the speakers for a
known-working set.
C. If A. and B. don't work, replace sound card with known-working one.
After you've done this troubleshooting, if you need more help post back.
