4. Check the Capacitors
If a newer RAM is also not working. You should check your motherboard further, You should check all the capacitors’ reading on the motherboard. You can replace the faulty capacitors or moist pads of your motherboard. If all of your Capacitors and moist pads are working fine. You should check other parts as well.
 
5. Check the Bridge
After checking the values of capacitors, you should check your Bridge. The bridge provides the power supply to the Display drivers and monitor.

6. Check the Resistors
Next step is to check the resistors between the ICs and RAM chips. They are used in a series. So you can easily find the faulty resistor and replace it with a new one.

Concisely, there is more than a 90% chance of just hardware rustiness or erosion problems. You just have to clean all the parts of the motherboard and replace some damaged or burnt parts of the internal chips like capacitors or resistors.
