While you're there, blow out the 'heatsink' with compressed air, it'll be totally clogged, they always are.
Another thing, which sounds utterly stupid, is try another power supply. I spent ages try to get an Acer laptop to stop crashing, freezing and turning itself off randomly. It looked exactly like a HDD problem to me, but it wasn't. Although the PSU was apparently giving a solid 19.2VDC off load it was obviously randomly dropping out. I had a spare lying around and it fixed the weird problems instantly. Cheap enough to buy a new one.
