unexpected sounds from board

Hi all ,

I hope find you well.

I have the above macbook 2008 and i am notice unexpected sounds from the logic board. this is not cooling fan noise and not hdd noice . I am notice that when I upgrade the logicboard of the laptop and ram to 5 gb ram and 60 gb ssd samsung. the question is if the sound is produced from ssd or ram modules or power mangment on logic board or from nvidia gpu or from wifi dongle. if ram module is not sit proberly can this make sound ? the laptop is fully functional and no problems at all ... Te person that sell me the board tellme that check it before sent out the board and no problems found but he didnt chek the charging ability because he dont have battery but i manage to charge the battery with out any problem... The sound is very low like sh electric sh but is low. Also the old logic board make a small amound of sound but i hope that was because the board is faulty,but now the new one also make sounds but is in lower level.

Any advice is accepted . Thanks!

This is why most techs only upgrade one thing at a time. Take it back to the original configuration and see if the issue persists. Then do one upgrade at a time to see exactly what causes the issue.

The strange situation is that that the laptop is belongs to my uncle and i dont have it before . But with the old logic board make again the same sound . Is this sound may be a common fault on this model ? I also try to check it with out the ssd because is old., to check if the ssd can make sounds.

Check the backward compatibility of the SSD drive. Your machine has a SATA I BUS running at 1.5GHz.
