It could be the keyboard and touch pad themselves, or it could be malware or a virus.

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.


For the touch pad, try the following and see if it fixes it...

1. Go into "Control Panel".
2. Click "Hardware and Sound".
3. Now click "Mouse and Touchpad".
4. Now go to "Additional mouse options".
5. The Mouse Properties window will open. In here click on your device.
6. Make sure your device is set to enabled. If it isn't then click "Enable Device".
7. Exit both that screen and "Control Panel".

Also, you might want to check for updates to your drivers, including the Synaptics drivers.

If this does not help, and an external mouse works fine, then it may well be a hardware issue.

Once you are done with these, I would still scan the system for viruses and also for malware.

You should be able to download an antivirus. If it isn't even letting you do that, then you should consider taking it to a tech who clear up the problem. They can also show you how to do this and other things to protect the computer in the future.
