Ok I never ran into this before but I have a three plus year old hdd wd 40 gig 7200 rpm....I'll start my comp os runs for a bit and then i'll hear a click ..like an hdd click or sound and then secs later lock up... reset and it works for hrs and then sometime after it will click and do the same thing....but after a reset it will work for another long time...I'll shut down and the next day same thing .....
My assumption is the HDD is getting old and weak.. Anyone think different ?
