I would like to share a simple solution I've used with a few laptops of these models (Turion processors) the symptomps as described are , the laptop turns on then after a couple seconds shuts down itself , no video at all on the laptop screen or external monitor.
Overheat on the GPU (NVIDIA G3) causes the chip to loose contact with the board , a reflow (circular motions with a medium/small nozzle at 300ºF during 5 minutes , previously applying resin flux with a syringe) on this chip restores the contacts and your laptop will be good to go.
Dont forget to througly clean fans and replace thermal paste/pads before closing it. Change the Northbridge, the heating does not help

Some people even mention adding copper shingles , but i never trusted what those might do to the processor/gpu in question. This is not the answer, but only to postpone the inevitable for a short time, the copper plate in this case will not help ...... if there is no specialized equipment, go to the service center ....

I agree, reflow mean not stable.
