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.

Do they keys stick at all ? Take a picture with a phone and then take the keys out and clean it "not with chemicals of course," or take a can of air duster and blow it out really good. This can sometimes solve stuck / non-functioning keys.

The key does not stick at all. im pretty sure some settings are messed up, however i dont know what since i havent changed anything. like i said, it works for a couple clicks then i have to hold both shift keys down for a couple seconds and it works again.
