Both Shift keys not working properly

[zzeninho]

For some reason, both keys do not work for most of the time, but can suddenly start working again as if nothing happened. When both Shifts are pressed at the same time, I noticed that the G and H keys are connected to 6 and 8 up on the numeric keys, and pressing G registers a 6, same for H and 8 and vice-versa. I have an Acer Aspire F15 F5-573G-519X

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.
