How can that be?

My laptop just crashes even though nothing is overloaded. It just turns off without warning. How can that be?

Did he have enough electricity too?

Yes he has everything

Cooler detached from the CPU => CPU overheats in seconds.

Find a tool to check the temperatures.

Can I do something about it? Does the room help? XD

The ultimate solution would be to reconnect the cooler to the CPU with fresh thermal paste.

A stopgap solution would be to buy a laptop cooling pad.

How should something like that be… And what do you expect here for an answer to such a meaningless answer?

When the laptop is booted, software works in the laptop. This can trigger something like this, for example; especially malware. There are also boundary conditions here: What was started up, was there any previous history before this phenomenon, was once reduced in the task manager and then something changed…
