"reboot and select proper boot device or insert boot media in selected boot device and press a key"

[Chip]

My recommendations are as follows.

Use recovery software +i.e. parted magic) to retrieve all important data. 

Throughly vacum and dust the interior of said machine. 
Purchase a new hdd and perform. A fresh install of os.  

Restore salvaged data from step 1.

Things break for no obvious reasons.  That is true of all electronic
and electro-magnetic components.  Possibly a poorly soldered
connection, possibly a faulty bearing on the disc, a faulty capacitor,
a cosmic ray through one of the chips, many possible causes.

By the way it is preferred not to top post on this list.  Please
insert your replies inline in the previous post as others have been
doing.  Thanks.
