Scrubbles has good tips. Make sure the system is clean and the fans flow freely. I would also try resetting the motherboard by removing power. This means AC power, the main battery and the CMOS battery. Let it sit for at least 15 minutes then put it all back and try. Laptops can also get dropped/mishandled, so sometimes errant behavior can manifest as a result.
