Reinstalled sound driver and now keyboard and touchpad aren't working

[roqayahaider]

Hello! This morning, my laptop's built-in speakers weren't working. I found a question here in this site and someone suggested to uninstall and then reinstall the sound driver, so I did. The sound is working and everything about this aspect is great, but when I installed the driver, Intel's driver installer setup some touchpad drivers, but I couldn't do anything about it so I thought it wouldn't affect the laptop. After restarting the laptop, the touchpad and keyboard won't work AND my laptop is not recognizing my heaphones.

What should I do?

System specs? Make, model, components, etc.?

OS? More details needed.
