Most likely, it's the cooling fan that has gone bad or maybe just dirt in the case.
Turn off the computer. Blow out the dirt by using a can of compressed air through the vent holes in the side and bottom of the case. If it still overheats, then listen for the fan to see if it's running. If you can't hear it, then it needs replacing.
The problem you describe is heat-related. Most likely, if you turn the computer off and wait 10-15 minutes, it will work again until it overheats in maybe 5-10 minutes.

There can be many reasons stemming from a simple solution, to ones that are not so simple.

Simple:
1.Laptops have an Air Intake Duct.
Draws air in to cool the various hardware components inside. (Mainly the processor)
Typically this duct is on the bottom of a laptop, and the laptop user blocks it with their clothes, bed linens, couch, or carpet.
->L-A-P-T-O-P
You would reason that you could place it on your lap! Not so! This can block that air intake duct with your clothes.
Same thing with sitting the laptop on a bed, couch, or carpet floor.
Solution?
Place the laptop on a hard flat surface.

2.Since the Air Intake Duct is typically placed on the bottom of a laptop, or on the side, this is a very good(?) area to draw up foreign debris.
Dirt/Dust/Hair/Food Crumbs/Lint, you name it.
Laptops just like any other computer need a regular clean out of that air intake duct.
Solution?
Use a can of compressed air for computers, and blow that duct out. (Charger removed AND battery REMOVED!!)

3.Along with cleaning your laptop's air intake duct out, I recommend buying a laptop cooling pad. Examples:

(They do list cheap ones and these work quite well!)

Not so simple:
After a period of time, a can of air may not be able to dislodge that foreign debris. The laptop needs to be taken in to a pro, where they will open the laptop up, and use physical means as well as air to remove the debris.

Fan running alot and laptop gets pretty hot


try using a can of compressed air to blow out any dust build up. also unscrew the panel(s) on the bottom and dust those out too but don't physically touch the parts inside. Also do not tip the can of compressed air upside down or anywhere close to a 60 degree angle which would cause foam to come out of the can.

Laptop starts and after a few seconds shuts down


Could be overheating, or possibly a motherboard gone bad. Try taking the battery out, unplug from power cord, hold down the power button for 20 seconds, put battery back in and see what happens.

I want to disassemble Gateway 450SX4


Nowhere: Only HP and IBM and DeLL offer parts schematics for their laptops. But if you take a look at some of those,you'll have a really good idea how to work on your Gateway,because they're all very similar.
