If you had a HP keyboard, it may have come with s/w that better allows to access certain features. Items like internet hot key, or other programed hot keys. You need to either delete such a s/w install at the add/remove icon in the control panel. Once done any other kybd. may behave better. That's not to exclude any h/w failure or malware at work. If you have simple basic kybd. it should behave. those kybd. with options, etc. could have done you in or the s/w that allows it.
