Lenovo G710 shutting down randomly

[MBech18]

Hello there
So today I suddenly started having an issue with my laptop randomly shutting down. Then instantly, it turns on again. It's fairly hot, but it shouldn't turn on again if it was because of an emergency shutdown.
I have plenty of battery left every time it has happened, and the power supply is connected
It happens every 2-3 hours or so, and it's making it pretty hard to do stuff.
I have also cleaned the fan thoroughly, but it was hardly dirty (I like keeping it clean).
Can anyone help me find a solution?

Hello buddy,
When your computer starts to shut down is there any blue screen?
If not... you can be a bit more calm for this machine.
1) You need to pure clean this laptop. Fans / powerblock / CPU FAN! If the CPU is overheated (you wont burn your hand...) the computer will go off.
2) If nothing happens your computer needs a doctor (the power is lost somewhere or some part of the computer is blown)
