I have a 2010 MBP.  I installed a crucial c300 earlier this year.  I am running snow leopard.
Yesterday, I ran into a situation where all my programs stopped responding, one by one. I could still use the GUI, but nothing worked, and eventually I had to power cycle.
Same thing happened today.
How can I begin diagnosing if am experiencing a hardware failure?
