i had to recently format my laptop,and the cmos battery was dead so i had to dismantle the laptop.since i had it opened up i cleaned up the cooling system and added some thermal paste on the processor,and it worked fine for like a day.and it wont power on.now no more.i had it in the service center they said it was a dead motherboard.i believe its the processor thats dead? i just need some feed backs whether the motherboard is dead or the processor? thank you in advance

and my reason to believe the processor is dead because i had the thermal paste applied on the processor.please help out

It's the motherboard. If the CPU was overheating, the computer would freeze before it allowed the CPU to overheat. CPUs are amazingly durable and don't just stop working like that with no warning. If you applied thermal paste, then you did the right thing, not something that would kill your CPU.

i applied it lightly but.it might have been too much and fried of my processor? can that be a possibility? i mean it worked for a day and the motherboard led's lights up.i've seen my friends laptop with dead motherboard and they dont have single led's lighting up.
