Hi, it's not the fan the problem, it could be the CPU, it all depend when the laptop is receiving a bad signal when it boots.

You could remove the RAM, and see if it will beep, remove the battery and power with just the adapter.

What you have, maybe, is a component on the motherboard is defective, this is the reason the laptop shuts down after around 3 seconds. Which component is defective, the only way is testing how the laptop is powering up, will reveal the bad part.

Yes it will be a wise choice, because troubleshooting the motherboard, you need experience and the knowledge of how the laptop is powering up. The best way to resolve your problem, if you don't want to go to a store for the repair, is to buy a new motherboard, it's cheaper than the repair.
