Laptop crash (groundless,?)?

It had been for a while that the laptop got stuck several times and that I had to crash it (unfortunately) to restart it.

But now it has even happened that the laptop crashed several times without reason. For example, that was when I wanted to open a document from the internet.

Just 5 minutes ago I played LS19 on the laptop. I just wanted to stop the engine on my harvester with the enter key. As I press the input button and suddenly out of nowhere everything is black and my laptop crashes. As if it was a crash button. I also have to say that I bought the laptop about 11 months ago on Ebay for 167.00 euro.

The seller I have already written time after the Kuf if it may be that he sold the laptop for this reason, but then he has never answered me. Do you have an idea what can be the reason?

It could be that he overheated. Simply unscrew and vacuum with the vacuum cleaner, the rotor. But it is important to hold the rotor firmly, otherwise it will break the engine.

So I have no desire that my laptop will break then.

These are. Sometimes even none of them screw Vienna. If you still power it is important to disconnect it from the power and then press again on the switch so that no residual current remains. Then it's almost impossible to break anything unless you drop it or almost dethrone with the vacuum cleaner.

I saw a video There are on my laptop on the side of such a shaft I then z.b. Let's suck it.

That will hardly bring the rotor will turn only fast
