EXTREMELY LOUD BEEPING ALARM FROM INSPERION LAPTOP

I have an Insperion laptop and at 2am this morning is started SHREIKING with an extremely loud alarm noise and woke up everyone in the house!

It said something about not finding the hard drive but I hit continue and it just started a Windows update.

HOW DO I MAKE THIS NEVER HAPPEN AGAIN????

There better be an option to turn this thing off. If not, I will probably remove the speaker for a temporary fix. Then I will buy a new laptop (NOT DELL) for a permanent fix.
