futhermore,I just bought it 15 month ago and it is still new.
I encounted the same problem before, and my friend said the hardware maybe too old and had to be disposed.
No clear explaination anyway...
Afterwards, I put it aside for months and it was normal again. But the problem came out again after a couple of weeks... so, maybe it's time for you to buy a new laptop.
Mostly not related to HDD problem, if so the system would --Hang--but would not turn off byself. Run virus scan first to check for possible cause. If problem still preset, try to remove one of the rams if you have 2 in your laptop, I think the cause may be either the mainboard or the ram.
