Does anyone know here i may be able to get a circuit diagram for a MSI 875P NEO-FISR. I have found someone who is able to help me he is an EMC manager at my work place and should be able to repair the problem. basically when i turn my pc on i get no beeps, no display nothing, i have bench tested, removed memory, chan ged PSU, tested PSU, changed GPU, nothing, this was caused by a power surge possibly becuase i put the USB cables in the wrong pins on my MOBO then pluged in an external USB Hard Drive. its definetly the mobo but i need a circuit diagram, can you help?

The chances of getting a circuit diagram for a motherboard are virtually nil unless you know someone that works for MSI.

The last time I saw a circuit diagram for a motherboard was for a Tandy TRS-80 and that was way back in 1979. The circuit diagram for a modern motherboard would be huge and buying it would probably cost you more than the motherboard itself.

Modern motherboards are assembled by machine. They have multiple layers and the chances of a mere human having dexterity to fix anything on a motherboard are equally slim.

AlwaysWillingToLearn, just in case you have any doubts, StuartS is absolutely right. You might want to consider this an opportunity to upgrade your system.

There are a few things on a MBoard that can be repaired. It is possible to replace capacitors with some success. chipset fans are another.

As the two posts above indicate there are 4 to 6 layers of traces on a modern MB.

Not only that, most of the parts houses will not sell to non-commercial accounts.

Gee, I miss the old tube testers.

I read it wrong and answer it wrong too. So get off my case you peanut.

Honestly i have no doubts about the advice i get from Stuart, he has given myself and others alot of useful and correct advice in the past as have all of you in fact. i honestly didnt know that a motherboard was multilayered, you learn something everyday

the guy that offered to help doesnt deal with motherboards so when i told him it was multilayered he just laughed lol.

I have updated my system, just finished it today, very impressed and happy with it.

This question related to my old comp which i sold to a mate, he isnt very happy, but i have found a replacement, thank you all so much for you help and advice.
