My computer crashed last weekend. All programs were lost. When I got it up again, there is no sound. And all the indicators show that no sound devices are installed. Please tell me how do I get sound back. Thank you.

Remove all USB attached devices like drives.

You may need to roll back system with System Restore. Under Safe Mode (press F8 during boot and choose Safe Mode).
Win 7 - Start > Start > Search type System Restore.
XP - Is Start > All Programs > Accessories > System Restore. Now choose a date prior to problem. You may have to try a few dates.

Uninstall last program(s) that was installed, again in safe mode.

To eliminate possible bad RAM. Unplug PC, open case, and remove all RAM. Test one DIMM at time, one slot at a time.
Re-install Windows. Clean install works best, but all data will be lost.

Lastly you may have other hardware problems. If it does another blue screen after reloading windows, especially with a clean install.

You may have to uninstall and reinstall with the disc.
