Dead motherboard?

[S3B]

Hello

First time here. From denmark

Here what's happing with my desktop;
1) Power on, pc dies and restarts it self. Fans runs...bios loading screen comes up (can't click on any buttons)...

Board speaker says 3x beeps with long intervals and then it goes on from bios to black screen.(here it sits for over 10min).

I tried to unplug psu, take battery out and add screendriver to two pins jumper. Nothing worked and also toke some components out one by one.


What is wrong here? Motherboard dead?or bios battery?

Could be PSU. Remove the RAM first and only use 1 stick at a time to test it with, you can also remove the GPU if you have integrated graphics although if it does work without it could still be a bad PSU.

You need to know who made your bios.
Once you know who made your bios you then search online for a BIOS beep Guide.
Quick search 3 Long Beeps, Keyboard or Keyboard card error.
