Make sure your speakers are not muted. Also, try plugging in headphones and checking for sound.
If no sound plays through headphones or speakers, and sound is not muted, you may need to restart your computer. If that does not help your soundcard drivers may need updated.

sounds as if you have a motherboard problem. If you are not comfortable in taking the bottom half of the case to see if that "crackaling noise" was.. then you can send it into samsung for repairs and estimate. If you are comfortable, first put your nose near a heat vent and see if it smells funny, like a little bit burnt. if so, its a gonner. You can look around once you remove the bottom pannals for burn residue or any signs of problems and report back if you need further assistance

There is normally a launch key manager of some type, which you open to designate certain programmes to the function keys, by means of a drop down menu to which you can change to Outlook. Look in your programme files for emanager, launch keys or similair.
