Can problem in the mother board damage SMPS?
I have desktop PC at my home. It is already 9 years old. Till now I have replaced SMPS 4 times. Recently when speaking with the computer repair person, he told me to change the mother board if I have to protect SMPS. As a electronics engineer I could only wonder why would somebody doubt on mother board? Is there a valid reason? Can a faulty mother board really cause trouble to SMPS? Given the fact that SMPS has failed 4 times I thought I should trust him. Please inform me if somebody has similar experience or knowledge on the same. Also what are the other reasons for the SMPS to get damaged?
