Laptop keyboard suddenly not working properly

I have a Fujitsu Siemens Celsius H270 laptop. My keyboard all of a sudden started to do weird things. It worked perfectly fine before, but for two days now, my keyboard only works properly when numlock is on. However, when numlock is on, I cannot use the function keys. When numlock is off, certain buttons do not work, for example, when I press P, it writes a star instead of P, other buttons, for example: K do nothing, so when I type K, nothing is written.Also when Numlock is off, I cannot type anything into the Chrome browser's URL bar, because when for example I try to type in google, it messes up and sometimes deletes what I wrote, or leads me to another website, like Facebook.I already tried uninstalling keyboard driver then restarting laptop, but nothing happened. Yesterday, I disabled Numlock on the on-screen keyboard and it fixed the issue, but today that does not work either. Disabling Numlock in the BIOS did not work either. I know, there might be some grammatical errors, but English is not my native language. But I hope you can still understand what I'm trying to say. Any help would be appreciated.
 
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.

Also, if your device uses one, you may want to try updating the Synaptics Driver if the above doesn't help.
