Try to clean the fans inside. No need to open case. Use an air blower to blow away dirt from the fans and heatsinks.
If that don't solve your problem, the cpu heat-sing or heat-pipe may be not seated properly. You may need professional assistance.

Cutting out windows

When the CPUoverheats it goes into thermal shutdown and will not boot up again until theCPU has cooled down.
The heat sink may be clogged with dust, which causes the CPU to overheat byreducing air circulation through the heat sink.If you are notusing your laptop on a flat surface, it may be obstructing the cooling vents onthe bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust.A laptop fanassisted cooling pad may solve your problem

Upper left keyboard area overheats and then it cuts out

Sounds like you have a laptop with a clogged fan or non working cooling fan. You'll need to open the machine up and clean and or replace that fan.

Fan runs constantly, then appears to overheat then switches off, only turns back on when cooled down?

Possible that the ventilation fan is blocked ,the filters are clogged. You will need to remove the covers to the ventilation fan, remove off all dirt-- do not place on the bed to cut off flow.
If the fan does not cool due to this clogging then the processor will heat up and cut off.

I have a compaq presario x6000. every time i place the laptop on my bed and turn it on it cuts off within 5 minutes. but when I place it on a desk and turn it on it does not cut off. do not understand why...

The reason is because when the laptop is placed on the bed the cooling vents are blocked and the CPU overheats and shuts down. When the laptop os placed on a flat surface there is sufficient clearance between the bottom of the laptop and the flat surface of the desk to provide sufficient air circulation.
If you wish to use the laptop in bed then place the laptop on a flat surface and not let the bed clothes cover the laptop's cooling vents.

Yes you could try a laptop "Cooler Pad" that may help, either that or go into the BIOS and set the temperature "Cut Off" point higher by say 10 - 20 degrees. Ensure the laptop has an air flow all around it at all times. Clean out your exhaust port, of dust etc.

Green light cuts off when plugging into laptop

Replace the charger, it probably overheat and died.
Try with a voltmeter to measure the output power (usually aroud 19 V DC)
Then the tricky part, try to power something else with the charger , something who might work with the output power (a car light bulb for exemple).
If it does work then you have a short cut on the motherboard of your laptop if it's the case replace the laptop, it's the hell of a job to repair the motherboard...
good luck
