This is a Compaq laptop, about 4 years old maybe. 1.8ghz P4, mobility radeon 7500, and 512 mb pc2100. The problem is, it turns itself off when under a heavy load like games or Prime95. It usually lasts around 30 mins when playing a game and Prime shut it down in 10. I'm pretty sure this is a heat problem, the keypad and bottom get pretty hot. If my system was unstable, it would just fail right, and not shut down? Is there any way I can fix it? I was thinking of opening it up, but then what would I do? Edit: now that I think about it, I did tighten the timings manually from 2.5-3-3 (?) to 2-3-2, though that wouldn't make it shut down, just fail prime or crash to desktop in games if it was unstable.
take a can of air to blow the dust out of the fan & pathways to the cpu. also can get an attachment that the laptop sits on that has fans on to help cool down the laptop
