I want to replace all the motherboard capacitors.... in doing i detached all of it and found out their are to types of voltages. but all of them looks the same.. that is why i'm confident to detached all that looks the same.. now im' having trouble puting the capacitors in proper place... my motherboard model is ms-7536 MSI... all i want is a copy of a deatailed diagram of the board which i could not find in the intenet.... tnx.

Re: I want to replace all the motherboard capacitors.......
For privacy purposes diagrams are not included when you buy a product. It's not available online too. It's either you can go somewhere in your place to ask for same motherboard or check the board again and hope that there's a voltage indicator mark on the board.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The Voltage Regulator is the Motherboard Voltage Regulator circuit, which is built into the motherboard, and not a separate module. Therefore not replaceable as a single unit, but at individual electronic component level.
The Radial Aluminum Electrolytic Capacitors, that surround the processor socket are part of the motherboard voltage regulator circuit.
A Capacitor slowly builds up a charge inside, then releases it all at once. Crude example would be a large swimming pool being filled up with a garden hose, then one wall of the pool is taken down all at once. (Some cameras use capacitors in their flash device)
Capacitors on the motherboard are used as Filters, and Voltage Regulators. The one's used as voltage regulators are in the Motherboard Voltage Regulator Circuit.
Some of capacitors used in the motherboard voltage regulator circuit, are used for the Processor. The 'Brain' of the computer.
A Processor MUST have a steady, 'clean', supply of voltage, and it Must be kept within tight tolerances of the Processor's voltage range. Cannot be too little or the Processor will not turn on. Cannot be too much or BIOS will turn it off.
Electrolytic capacitors have an Electrolytic Paste inside. After time the paste breaks down. Chemical decomposition. It's normal.
Computer engineer's know the paste breaks down after time. They use a capacitor, or capacitors, that are rated at twice of what is needed for the application.
This way when the capacitor's capacitance breaks down to 50 percent, it is still 100 percent good for the application it is used for.
Designers have come up with a deterrent to this problem. They are now using solid Polymer capacitors.
My solution is based on that your motherboard has Electrolytic Capacitors on the motherboard. Some of the newer motherboards use both Electrolytic, and solid Polymer capacitors. For this design of motherboard I am referring to the Electrolytic capacitors, also.
Solution? If the motherboard is bad replace it. Of course this all hinges on if it is feasible. Cost of motherboard compared to replacing the computer.
Post in a Comment if this is your problem, and post the computer manufacturer name, and Model Number. The Model Number can be found on the back of a desktop computer, next to the Windows product key, or up on the side of the computer tower.
[For an HP or Compaq computer this is on a white Service Tag. P/N = Product Number, and the number I need ]
This way if you like, I can look up the price of a replacement motherboard, and see if this is a feasible alternative for you. Then I can guide you in replacing it.
Your power is the issue here, either the PSU is damaged or the Motherboard, you can buy a PSU tester to find out, can be bought on ebay and so forth however make sure all your connections are firmly attached ect
Generally this means a bad Power Supply, or bad Electrolytic Capacitors on the motherboard.
I wish I knew what exact eMachines model number, you were referring to. Because I do not, this solution will be generic.
Looking at the back of the computer tower where the power cord plugs in, this is the Power Supply. (Rectangular in shape metal case, has it's own fan)
eMachines are a budget computer. Designed to save the consumer money, while trying to provide a medium design of personal computer.
However, in saving the consumer money, there are less than quality parts used. The Power Supply is one of them.
(IF I had the model number from the back of the computer tower, next to the Windows product key, or up on the side of the tower, I could give you exact Power Supply replacement options, and guide you in replacing)
One of the main electronic components that break down in a Power Supply, are Electrolytic Capacitors. They are the 'weakest link'.
The type of Power Supply used in a personal computer is an SMPS. Switched-Mode Power Supply,
Click on the photo to the upper right. The two round blue circles are Electrolytic Capacitors. This is a top view. The blue circle is the top edge of a plastic sleeve, which goes around the capacitor's body.
The letter E also points out more Electrolytic Capacitors. Top view. (The ones in B are Input Stage capacitors. They filter the incoming AC electricity. The ones marked by the letter E are Output Stage capacitors. They filter the outgoing DC electricity )
This is a side view of an Electrolytic Capacitor. (Radial Aluminum Electrolytic Capacitor, to be more exact),
The one at the bottom with the light blue sleeve, and 160V, and 10uf, on it. It is a Radial Aluminum Electrolytic Capacitor)
This is not an invite to replace these components. The preferred method is to replace the Power Supply. (A good capacitor can hold a charge for weeks, months, sometimes over a year. The charge can be released to YOU, if the capacitors are not Properly discharged first)
Bad Electrolytic Capacitors on the motherboard. (Again, these are also Radial Aluminum Electrolytic Capacitors )
Part of what Electrolytic Capacitors do on the motherboard, (In referring to the motherboard's capacitors in your eMachines), is to regulate voltage. This is the Motherboard Voltage Regulator Circuit.
Part of what the MVRC does, is to regulate voltage for the Processor. The Processor MUST have a steady, clean, supply of voltage, and it MUST be within the voltage range for the Processor.
Can't be too much, or too little.
The capacitors that make up the part of the motherboard voltage regulator circuit, that handles voltage for the Processor, are in a Series circuit. Just like Christmas tree lights. If one capacitor goes bad, none of the rest will work.
A short video (Not made by me) showing what happens when Electrolytic Capacitors are bad on the motherboard. (These 'caps' also are in the motherboard voltage regulator circuit, that handles the voltage for the Processor),
Hi, Do this, check-up motherboard capacitor parts (observe for burn,low voltage and open voltage) using voltmeter(tester) change and replace it. your motherboard loose and defective parts specially capacitor parts.try also clean your motherboard using contact cleaner or alcohol. need have continues beeping if hear that the motherboard working good. sample capacitor parts of motherboard.
1) I have to assume that you installed the caps in the correct direction, observing the polarity. Otherwise they would explode. I should state 'probably' because I have never installed a cap backwards. Do not know if they explode every time, or not.
Point is if they do not explode every time if installed backwards, then see if you have installed them correctly. Line the Negative polarity marking on the cap, to the Negative polarity marking on the mobo. (MOtherBOard)
How close did you get to the stated uf, (Microfarads), and voltage?
2) As I am sure you are aware, it is the Electrolytic paste going bad inside, and forming a gas, (Hydrogen Gas), that expands, and swells the cap's case. Sometimes though, there are no visual signs of failure, as the paste just dries up inside.
3) Capacitors are used as Filters or Voltage Regulators.
Ones in the general area around the CPU, are part of the motherboard voltage regulator circuit, and this part of the motherboard voltage regulator circuit is for the CPU. (However read on) These caps are in a Series circuit. Just takes one cap to be bad, and the circuit fails.
The caps around the expansion slots, and ram slots are in a Parallel circuit. Takes more than one going bad to mess things up.
However, just to add confusion to the matter, the motherboard will Not have the motherboard voltage regulator circuit capacitors, that handles each specific hardware component, IN it's general area.
For example, the part of the motherboard voltage regulator circuit that handles voltage regulation for the CPU, may have capacitors located across the board from the CPU, plus the one's that surround, or are in close proximity to the CPU.
There may be a cap that regulates voltage for the CPU, and it could be clear over on the other side of the ram slots, or down next to an expansion slot.
The motherboard voltage regulator circuit, has a high ratio of being what fails, when a motherboard goes bad.
The motherboard voltage regulator circuit is composed of Chokes, Transformers, and Electrolytic Capacitors. The Electrolytic Capacitor, (Radial Aluminum Electrolytic Capacitor), is the Weakest link.
Especially when the world market was flooded with a deluge of bad Electrolytic Capacitors, and they are still cropping up today in all kinds of electronic components. Not just computers.
Point? You may want to follow the above link, and see if you can figure out the voltage regulator circuit caps, and replace all of those that didn't get replaced, or replace every cap on the motherboard.
Sounds extreme, huh? Understandable.
But how much do those caps cost? How much does a replacement board cost of equal value. (About the same as all of the caps, probably)
Is this just to see if you can do it?
[ I'm a computer geek, and I probably would. In fact I have, but not to the extreme of replacing all the caps. It could be the motherboard chipset next, (Northbridge/Southbridge chipset), so you have to keep things in perspective. You won't be replacing the motherboard chipset. But if you do, WE ARE FRIENDS! lol!]
Video processor being what? The Nvidia GeForce 6100, Northbridge chip? Under the 'Meat tenderizer' heatsink. Large one on the side towards the I/O ports?
Are YOU sure the PSU is good? No doubt in your mind what-so-ever. A PSU with a weak voltage power rail will light LED lights, maybe spin fans, but will not have enough power to turn the Processor on. No Processor, no video signal.
Just stating in case you pulled a PSU out of your parts pile, to see if you had those mobo's fixed.
First you have to check where the oil type liquid came from. Because this oil may come from the power supply unit, if so change first the power supply unit. Second check if the electrolytic capacitor in *********** board has liquid oil in vicinity. Capacitor may leak if the temperature is over or voltage supply is over the withstand voltage rating of an capacitor. I recommend to try replacing the power supply unit. Good luck.
Short for voltage regulator module, a small module that installs on a motherboard to regulate the voltage fed to the microprocessor. Nearly all motherboards have either a built-in voltage regulator or a VRM, the only difference being that the VRM is replaceable. the cost is about $80 USD
