My first thought would be a heat issue as others have suggested. Also I've seen
the internal fans get caked with dust and start dragging or not spinning at
all.
Some are easy to get to and clean, some not. When my HP laptop hard drive
started to die, the laptop did this also but wouldn't always slow down first -
screen would just go black and power off. Thermal take used to make a side slot
mounted cooler that pulled the hot air out a side or back vent and it has a usb
plug for power. I picked up three for $2.50 each and still use them all. I have
one on the back of the PS3. It has little spring arms that clamp hold it on any
slot with little verticle openings.

Lol, hey Tim-so yeah I was noticing that this laptop was getting hot in the
past
(it is a i7-740QM with a ATI Mobility Radeon HD5650), but the irony is that I
DO
already have a cooling device under it-b/c the first time it happened yesterday
I thought it was likely heat related so I put one of those cooling fan trays
under it and even positioned it for maximal cooling, and it feels cooler, so I
thought I'd eliminated heat as an issue, but maybe not...hmmm...
Well, in case it's not that, what would you suggest I use to test the HD and
see
if it's having issues? Thanks for the comments and help! This thing is only a
few months old too *grumble, grumble*

Hello Bino,
Before doing anything drastic to the Laptop have you noticed or observed the
bottom of the laptop and see if it is getting hot. If so try using a laptop
cooling device to see if it reduces the problem. Usually heat on Laptops cause
the Laptop to shutdown or restart.
If you said it would restart and you tested the memory, look into the hard
drive. The hard drive could be going bad or creating bad sectors and needs to
be backup'd and replaced.
I hope this helps you out, good luck and best regards,
