Issue in System
-
I went to client place found the system not booting.I have checked the power supply.There was a issue in SMPS and then changed new SMPS.But the system does not boot into the Centos.When I tried to start the system with other system DDR2 RAM.The same error where the system does not boot.The processor is spinning but there is no display shown.Then,I took the CMOS out and reinserted the CMOS.Then jumper pin is also changed and after that also the same issue was Found.The issue is that the system is not booting to the OS but the processor fan is working.How it will be like this?The VGA cable for the system is changed,Power chord is also changed and after the new monitor also changed but the system does not boot.What may be the reason for this issue?

Have you tried powering it on and letting it boot and then tried SSHing in?
It could be the onboard video is fried. The HDD could be fried. The motherboard may be receiving power but do you see a POST or hear any system beeps? If you aren't hearing any beeps or seeing a POST, then your motherboard could likely be the culprit.

A lot of motherboards have a very small amount of onboard memory, usually anywhere from 32-128MB. So it'd still boot even without RAM, but it wouldn't really run. Have you tried installing a graphics card and plugging video into that? I bet your motherboard is fried.

I need to know which component is fried in the motherboard.How to resolve the issue? -

Or replace the server depending on the age.

@thanksajdotcom OK My client is not interested to replace but he want to identify the component and he wants as to Solder the board

That is NOT a good idea. Replace the whole motherboard. To identify the individual component, you would need a testing probe and the electrical schematic for the specific motherboard. Enormously time consuming. You could walk to China to get a new board quicker. Just because a 79 cent capacitor is blown does not mean it is a reasonable repair.

Totally agree with this. DO NOT ATTEMPT REPAIR! This is a waste of both time and money. Replace the board and be done with it. You're client is being a moron if he wants to do this.

Holy crap... that is such a bad idea, do you or anyone on your team have experience soldering integrated components? The majority of the time those solders are done by a precise machine at the manufacturer. Buy a replacement board.

Exactly.

SMPS is the Switched Mode Power Supply. It you may have a surge or some other issue, If you have checked the Power Supply output voltages or confirmed it with a tester it time to have the system replaced either under warranty or buy a new one. It likely took out the motherboard sensitive filter circuits with it.

You can do it. But it's not worth it. You shouldn't attempt if at all if you have never dealt with it. Surface mount components are not easy to solder by hand.

There is no need to test in this way as there is no way that it can function. It's like trying to start a car with no gas - you know it won't start, so it doesn't tell you anything that you didn't already know.

The processor fan is just a fan. It turns on when there is power. It does not indicate anything other than some power is getting to the board.

That's not a reasonable thing to do.

To be Fair most will still give POST Beep codes without ram. However your likely just going to get a RAM ERROR code. So that's pointless to help you.

What the client is interested in should not be your only concern. This is not an IT task. You need an electrician here, not IT. The board is not meant to be repaired in this way, chances are even if you figured out what is wrong you would destroy the board trying to replace it. Clients will demand anything that you let them demand, do not let them make irrational demands that make no sense. You are the IT consultant, you have to tell them what is and is not possible. If you do not, they will simply make up anything that they want and be mad at you for not being able to do it.
No one here is going to be able to help with this as this is not an IT thing. IT does not solder components. Rarely do we even replace motherboards, but that's a transition task (between bench work and IT.)
Quite literally, in 26 years of working in IT, I've never heard of someone ask for something like this. Which should indicate just how unreasonable your client is acting. Don't let this be an option. Simply dismiss it as a joke, as something he would be crazy to have said. Don't let him think for a moment that you actually considered trying to do this.
