Luckily that is pretty easy with modern motherboards.

1. Remove power and unplug all devices hooked to computer.
2. Open case.
3. Write down the location and orientation of all wires connecting to old motherboard.
4. Disconnect all wires from the case that are plugged into old motherboard.
5. Uncrew the screws holding the motherboard in the case.
6. Carefully remove old motherboard.
7. Install new motherboard and secure it to the case (probably using the same screws as the old MB)
8. Refer to diagram you made earlier to plug in all the wires to the proper places in the new motherboard.
9. Check and make sure the new motherboard works before closing the case.
10. If everything is working correctly, close up the case and you are done.

SOURCE: Dell sx270 optiplex

Its easy on most dells, open the case, disconnect all the cables and remove anything in the way, then just unscrew the boards fastening screws that hold it down. Sometimes its a single screw that holds the board in place, once removed, the board slides out. First try reseating everything, Pull out the memory and put it back in, same for the video card and any other devices, unplug it also and pull out the bios battery for 30 seconds so everything resets.

If the Capacitors on the mother board are swollen or have discharge, then the board is what went bad, The capacitors are the round black cyclinders that stick up from the board, there supposed to have flat tops, like tiiny little soda cans, but when they get heat damage or go bad, the get domes and split at the top and eventually rupture.


Here is the link to the dell site for the repair manual.

You can also go to ( www.support.dell.com )

In the middle it has a link to MANUALS, then it has a way for you to look it up by make and model of your PC.

SOURCE: need manual for l-nc51m motherboard

You did not mention which ThinkCentre model you are using, but I know that the Lenovo 3000 J115 is using this motherboard. Look at the hardware manual from Lenovo (link) and see if that is what you are looking for.

You can also try to locate it yourself (link)

If this is not the right one for you, just come back here and leave a comment with more details about your computer - I'm happy to help.

Where can I get instructions to put unidentified tower together?

You have all the pieces .. motherboard .. cpu .. ram .... heatsink/cpu fan?

Place the cpu into the motherboard socket. Note that it only fits one way. Check the pins on the cpu against the holes in the socket. Hold it in place with the securing catch/lever that you will see on the side.


Smear some heatsink/cpu paste onto the top of the cpu. The heatsink paste is basically a 'heat resistant glue'

Put the cpu cooling fan onto the cpu and screw it into position. Or, it may have a securing lever to hold it in place.

Put the RAM into the ram slots. They only fit one way. Make sure they are firmly in place.

Put the motherboard into the casing. Align what holes you can and use the screws that come with the casing to secure the motherboard.

Connect the casing power supply to the motherboard. Note that it only fits one way.

Connect the cpu cooling fan to the motherboard connector. It only fits one way ..

Next, look at the leads that are just lying loose .. the small female 2 pin connectors will be marked 'PWR' ..'LED'..'RESTART' ... There maybe 8 of them.

On the motherboard identify the block of male 2 pin connectors. The female connectors must connect to them. You'll need good eyes and probably a flashlight, as the writing on the motherboard is small..

If you are connecting a sata hard drive, connect to the motherboard connection that says 0. Connect your dvd drive to '1' Again, notice that sata leads can only fit one way.

Then connect any video or sound cards to the motherboard (if any).
Just look on the motherboard for anywhere the connecting wires will attach. You won't go far wrong.

The casing won't come with instructions of 'what to do' as such. If there were instructions there it would relate to pin/hard drive connections.

What you CAN do is a google search. If, for example, your motherboard is an ASUS 123456 .. search for 'ASUS 123456 motherboard connections'. Or log onto the motherboard manufacturer's website ..

Display ic

On that one, itis the big chip beside the CPU socket. It is basically most of the chips a motherboard has, in one chip. If it goes,the whole motherboard is considered gone. If the graphics portion is gone, then a PCI card might help. It could be bad RAM also.

Quite frankly, the whole system is considered obsolete. The least you can do is see if you can get a motherboard which fits in your case, and can accept the existing CPU and RAM.

Need new motherboard for Aspire T160. Where can I obtain one and how much do they cost?

Hello Martyn - Acer does not sell replacement motherboards. You would have to send your PC to Acer (no longer under warranty) for them to replace the motherboard, charging you for the hardware and the labor which, frankly, would be more than the worth of the whole computer with everything in it.

Fortunately your computer can use any Micro-ATX (a standard "size") motherboard. My suggestion would be that you take your machine to a local PC shop (if such is relatively local) and tell them you would like a new motherboard in you PC and want to keep your old CPU, hard drive, CD/DVD, memory, and any other parts that can be reused which should be everything (except if the dead motherboard damaged other parts like the CPU or memory.) If you wanted to it wouldn't be that more expensive to replace it with a newer faster motherboard but then you would have to replace the CPU and memory also.

I'd estimate (in the US) that it would cost about $150-$200 to replace the original motherboard...it never hurts to shop around.

Good Luck and Thanks for using Fix Ya.

I have been searching the world for an Albatron KM18G Pro Motherboard to replace one that has fried. Do I need the motherboard to be exactly the same?

No you don't. Find out what CPU you have and what socket is on the motherboard (it will be printed on the CPU socket).
Then look at the memory to see what speed it is.
Now look for a motherboard that supports both that CPU socket and that memory type/speed.
Everything else just goes along for the ride. (Video card, though--do you need on-board video or do you need a socket to support the external card--check that, also)

Wont power up ecs motherboard

Your 4-pin power connector supplies voltage to your CPU through some series of MOSFET transistors. First try to disconnect your CPU from the socket and power up your motherboard. Your CPU might be toasted. MOSFET transistors might be bad. Also look at your big caps around the CPU. If they have bubbled tops, you need to replace them.

Good luck
