HP Pavilion not starting up

[CoolKool]

I was watching Youtube video when suddenly screen turned blue with following message:

Your PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you.

0% complete

stop code: CRITICAL PROCESS DIED.

 

This above blue screen stuck forever and I had to press power button to stop and restart but now its not booting and following message coming:

 

Hard Disk Error

Please run the Hard Disk Test in System Diagnostics

Hard Disk 1 (3F1)

F2 System Diagnostics

When I press F2 and try to run either Quick Check or Extensive check it says  SMART Check or Long DST "NOT INSTALLED"

Please help me out
