How to diagnose a failing component on a motherboard?
Recently I inherited this laptop. The problem is that when I boot it on, there are two beeps on loop and the laptop didn’t boot on. According to the Dell website, those beeps mean that there is no ram installed. I tried with some different RAM sticks among the other RAM slots, but there is always two beeps no matter what, so I imagine that the problem is on the motherboard.
I have a multimeter at home, but I have no clue how to diagnose the motherboard to find the component that is failing.
Can anyone give me some advice?
Thank you very much.
These are the pictures of my motherboard:
