keyboard random keys automatic typing

[nirbhai.twp]

i have a z50 Lenovo laptop , the problem started a last month when the End key went uncontrollable long press typing for which i thought the specific key was damaged .. but after a while it shifted to number pad 2 (alternate down arrow ) key and the end key now is fine ~ so key is not damaged but the problem is something els... Can't seem to find a good enough solution and wondering if its some sort of virus. Hope i get a reply coz this is annoying me as hell.
btw, the typing does stop for a small interval when i manually click the specific key but then again repeats it after a while.

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 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.
