Keyboard and Mouse sensitivity

Hi,

I have never had  Keyboard and Mouse sensitivity problems before.

I have bought this DELL 5500 computer and ever since I have to press my keyboard shortcuts a few times to get responded.

Once it's reponded it's okay after that, but if I close and reopen it will happen again.

I've been play with mouse setting and all that but didn't help.

Any word of advise or comment will be greatly appreciated.

Thank you.
