Switch not turning on buzzing sound coming from motherboard


Im having a issue where the switch will not power on, with or without the battery powered on.
I tried changing the battery with a known working battery but still wont power on.
When I plug in the power cord without the battery plugged in, I can her a buzzing noise that sounds likes its coming from underneath the CPU/GPU shroud.

Does anyone know what the issue might be?

Ok after geting a new multimeter I have found some shorting capacitors, where should I start looking next?
