Could be a heat issue, I know some motherboards will shut themselves down if they are getting too hot, if you have completely formatted the laptop and re-installed XP and it still does it then it's gotta be a hardware fault.

Get it looked at, at a PC repair shop.

When you are using the laptop, where is it sitting?
On a table, on a chair arm or where?

Basically what is underneath it and how much free space is there for air to circulate under it and around it.

Some people put a cushion on their laps so that they don't get too hot and then wonder why the laptop cooks.

Sounds like it could be a heat issue. It most likely needs a good clean out from dust.

Yoiu would be surprised how much dust and dirt get into a laptop in four months. Dust builds up and static bonds it together.
Have another go at cleaning out the case interior and the fan.

Try a short piece of wood (the length of the back of the laptop and about 20mm x 20mm. Place it under the back edge of the laptop and this will tilt it towards the user slightly, but not really detract from the typing. It will allow plenty of air to circulate underneath it .

down load a copy of speed fan (its free) you can keep an eye on the temps of the heat monitor sensors and see whats getting hot.
