Question Laptop screen randomly goes black ?

[laron9er]

Laptop model: Lenovo Flex 5

it has Ryzen 7 5700U CPU and is running Windows 11. It has been almost a month. The laptop screen randomly goes black and reboots. I tried disabling processor performance boost mode from the power options, but it did not help.

test with an external monitor?

what do you mean screen reboot?

The system shuts down abruptly and restarts.
The event viewer shows these events before the shut down.
So, is this because of cpu overheating?
Also what can I do to solve this.
