did you try a system restore?
Info on System Restore (as previously mentioned) http://www.microsoft.com/windowsxp/using/helpandsupport/learnmore/systemrestore.mspx, http://support.microsoft.com/kb/306084.
Otherwise - check out Device Manager (Start, Run, type "devmgmt.msc" (no quotes), press Enter. (You will require local administrator privileges to make hardware changes). Make sure that all devices are installed (no yellow exclamation marks or question marks on devices - also check for red crosses  - indicates disabled hardware)
Simple thing first - check Sound & Audio Devices in Control Panel, make sure that sound is not muted.
On some laptops you can turn the sound of with a key on the laptop too... If everything looks ok on your system, check the switches on your laptop to make sure you haven't accidentally switched it off.

the multimedia Audio Controller has a question mark...I suppose that the driver is failing. Do I have to have the installation Cd's of my computer.?
Hi. Thanks - hope that you find the correct drivers.
Check out the Resources tab after you r-click on the sound device in Device Manager, and click Properties. Select Hardware IDs from the drop-down list, and take note of the code following VEN - then take a look at www.pcidatabase.com, and search for the code that you found. For example, DEV_8086 is Intel. You should be able to isolate the driver make and model from the Hardware IDs information. You can also search for the DEV code to find an approximate match for your hardware. Good luck!
