The key '7' and the space bar was working automatically even before entering my password so after a long lasting trouble I uninstalled the driver of the internal keyboard . But now I can't find the website to download the driver again. My model is hp pavilion 15 au006-tx. Please provide me the link to download the internal keyboard driver.
You shouldn't need one. A link that is, the computer is capable of fixing this on its own... Try this...
NOTE: If you need to type in a password to even get into Windows to do the following, make sure you attached an external keyboard first, to get past the password. Then disconnect the external keyboard and try the following...
1. Uninstall the keyboard driver.
2. Reboot the computer (without reinstalling the driver).
3. When it restarts, it should reinstall the driver on its own.
If this doesn't work, you may wish to try connecting/reconnecting an external keyboard and see if it works fine. If it does, then it could be the keys themselves that are the issue.
You may also want to try updating the Synaptics Driver if the above doesn't help.
