Question Asus N53S keeps shutting down from BIOS

[NickvT]

Hello,
I have a strange problem with my Asus N53S laptop.
When i start the laptop and enter BIOS (by pressing F2), it will shutdown completely in less than 10 seconds, making it almost impossible to change settings.

However, when i boot normally into windows, it will function normally and never shuts down in any program.

Does anyone have an idea where to look?

PS it's not running hot, fans are working normally and are clean. Its specificly the BIOS that makes the laptop shuts down.

Do you actually see the BIOS menu in that ten seconds, or is the screen still loading?

I can get in the BIOS already and for a few seconds browse or change pages and if i press F10 quickly enough i just reboot fine. But when i stay inside the BIOS it shuts down without warning.
