If the cpu - processor - is overheating, the computer will work fine for a while after it has had a chance to cool to room temperature, then when the cpu gets too hot the motherboard's bios will shut off the motherboard, and the computer will not start up again normally until the cpu has cooled off to below some temperature,
If this is happening on a desktop or tower computer, then the problem is probably caused by too much dust and lint on the cpu fan and cpu heat sink inside the computer case.
You should get an adult to do this:
- unplug the computer
- remove the left side panel as seen from the front of the tower
- look at the cpu fan and heat sink
- remove any dust and lint on the cpu fan and heat sink, but DO NOT use a vacuum cleaner - e.g. use smal artist's paint brushes, small paint brushes, or you can buy canned air or gas meant to be used for this purpose at places that sell computer parts
If this is happening with a laptop or netbook - don't get anything in the way of the holes in the bottom of the case that let the air in and out - e.g. don't use it in bed, or on your lap, unless you have it on something flat such as a TV tray or a metal cooking tray like you bake cookies on in an oven..
