Replace the motherboard.
My laptops motherboard (CN-0HNR2M) works not correctly..
when i push the switch button,it starts working,but after 30 seconds it shuts down automatically..than i disbanded it and used new thermo paste on CPU,and the thermo pillow on GPU,north and south bridge chipset.but nothing has changed...i cut off the yellow cable of CPU FAN for working on the highest speed,but GPU is still HOT,and the laptop shuts down like emergency....I think there is some kind of problem of any little resistor,or condesatore and GPU gets so high voltage and that's why it gets HOT (between 70-85 celsius ) ..
So what can i to do ?
thanks a lot
