Here is one site that sells the motherboard:

Also look at:

They are kinda expensive, at least $150

Get a new motherboard Asus A8n-LA http://www.buy.com/retail/product.asp?sku=207999853&listingid=28062318&dcaid=17902
Even comes with an intergrated video card like your old motherboard. If you have seprate video card, go with a ASUS A8N-SLI Deluxe, its allot better.

You can also call valuerecovery.com they will repair it for $55. There is a chip under the heat sink that goes out. I just had the same thing happen to me for the second time. I googled and found a new motherboard through tigerdirect part search. There is also a place in Wis. called KamCom.com were you can purchase refurbished boards. Hope this helps.

I would try to look on e-bay for a replacement motherboard. One thing that might help is to replace the power supply, also. Although I've never had to do this to make the problem go away, it would be the next best thing to having to replace it a third time.

Good luck

My optiplex 960 does not turn on. the number 3 flashed for a second. I replaced the motherboard. Now the 3 flashes for a second or two, then turns off and then the 1 and 3 lights blink.


Dell Support > Optiplex 960 > Manuals & Documentation tab > Service Manual (6460KB),

http://www.dell.com/support/troubleshooting/us/en/19/Product/optiplex-960

A) "Light Pattern,
Number 3 - Blinking Amber -
A possible motherboard failure has occurred"

This you must have known........however going on.........

"Number 1 and 3 blinking amber -
A possible motherboard, Power Supply, or peripheral failure has occurred"

The first thing to check with desktop computer failure, is the Power Supply.

If we are to agree that using the motherboard diagnostic LED's, and specifically the No.3 LED was blinking Amber; then we can agree it was motherboard failure in the first place.

However, me? I'm a skeptical computer geek.

I ALWAYS, test the Power Supply's 3 main voltage power rails FIRST, then I may go on to assume diagnoses has led to the motherboard, peripherals, etc.

From there, it's check the Radial Aluminum Electrolytic Capacitors on the motherboard, for visual capacitor failure.

The motherboard chipset going out, is a Rarity.
IF, it does fail; it's usually the Northbridge chip of the motherboard chipset; because it get's the hottest.

(That's why it has an aluminum finned Heatsink on it. Sometimes Southbridge chips do too)

Southbridge chip is next in line.

You don't know how many desktop computers, I have fixed over the years; that the problem was the Power Supply, and not the motherboard, as assumed by the owner.

Also it's all over the internet.

LED's light up, and fans spin; and people assume the Power Supply is OK.
This = No.

1) If ALL of the LED's were lit up at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor (CPU) uses 51 to 130 Watts of power.
Just depends on what Processor it is.

Therefore a Power Supply with a weak voltage power rail, will have PLENTY of power to operate those simpy little Light Emitting Diodes, and maybe spin fans; but will NOT have enough power to turn the Processor on.

Either test the 3 main voltage power rails, with a multimeter set to DC Voltage, (3.3 Volts, 5 Volts, and 12 Volts),
OR,
Use a KNOWN to be good, Compatible power supply; for a temporary test unit.

http://en.wikipedia.org/wiki/Computer_power_supply#Wiring_diagrams

http://www.playtool.com/pages/psuconnectors/connectors.html

Power Supply deemed to be good? Go on with the diagnoses.

Visually inspect the capacitors on the motherboard,

http://capacitorlab.com/visible-failures/index.htm

http://www.youtube.com/watch?v=Lut7MX5Dd_A

What? Are you cra-zy Joe? Did you not read I replaced the motherboard?

Ahem,

That motherboard you have, IF a direct replacement; is an NOS.
New/Old Stock.
Been sitting on a shelf for years.

Point?
Electrolytic Capacitors break down over time. It's the 'nature of the beast'.
They have Electrolytic Paste inside, which is a chemical.
It's known to break down over time.

Computer engineers know this, and use capacitors that are rated at TWICE what is needed. 200 percent.
So..........when the capacitor breaks down to 50 percent good, it is still 100 percent good for the application.

Point?
New purchase, or not IMHO it could be a bad motherboard.

Another point of interest; Electrolytic Capacitors do NOT always show outside visual signs of failure.
The Electrolytic Paste inside can just dry up, instead of developing a gas, (Hydrogen Gas), and not break the seals of the capacitor.

However, I would make sure the power is good, then disconnect all internal peripherals.

Peripherals are also the Harddrive, as well as the optical drive (CD/DVD drive), and Card Reader or Floppy drive.

(Outside peripherals; Keyboard, Mouse, Monitor, Printer, etc.
Leave Keyboard, Mouse, and Monitor of course; but disconnect any other outside peripheral)

That means disconnect the data cable from Harddrive to motherboard, and power cable to Harddrive.
Also same for optical drive/s.

Disconnect, the two cables from the USB header on the motherboard, for the Card Reader. (media)

Floppy Disk Drive data cable, and power cable, IF used.

LEAVE the front computer case fan connected, as it's cooling for the Processor. Ram Memory is installed also.

(NO graphics card if you have installed one. Connect monitor cable back to the motherboard. {Back of computer > I/O area)

So essentially we are talking just Processor, processor fan, and Ram Memory.

Turn the computer on.
Try to pull the BIOS Setup screen, up.

If no, you have a bad motherboard.

Now remember, this is AFTER the Power Supply has been deemed good.

BIOS Setup screen comes up?
Then reconnect the harddrive.
Good to go?

Then reconnect the optical drive. If drives, connect one at a time.
Check.
Then connect the second optical drive.

Good to go?
Then reconnect the card reader.

Had a post from someone on here not long ago; that we went through diagnosing; until he found out the Card Reader was the problem.

If memory serves it was one of the cables, coming from the card reader.

I'm guessing he ran a continuity test on the cable, with a multimeter set to OHM's, to check whether it was indeed the cable; or the USB header on the motherboard it plugged into.

He never stated.

Arranging all that prattle I stated above.......I mean Summation:

1) Test Power Supply voltage power rails, or use KNOWN to be good, Compatible power supply

2) Visually inspect Capacitors on motherboard.

3) Processor, processor fan, Ram Memory, ONLY; see if you can get BIOS Setup screen to come up.

My computer time and date keeps resetting itself to a different time. I'm connected to the internet but that is all. Why does it do this?


the clock microchip inside you motherboard is run by a small lithium battery model # CR2032 ( the size of a small coin) this is embeded in the motherboard, this can be replaced with a new one by removing the PC's cover and looking for it on the motherboard .....once replaced the clock can be re-set to the current time....once the machine displays the Desktop screen....

Hi,
Inspect the memory slot carefully. If there are are bent pins in the slot , you can probably align them with a pointed tip. Otherwise the best option would to replace the motherboard. Because after the process RAM is the fastest component in the computer. Out of experience in repairing the motherboards ,i recommend to replace the motherboard.

Thanks Fixya

This is the problem with your "Bios Battery" which on the motherboard. Maybe there's none or it's not functioning anymore. Just replace it and the "cmos checksum bad" error message will go.. for your reference, i include some pictures.. herein. 0748746.jpg

Deep freeze computer inresponsive


it sounds like your computer power supply went bad.
go to your local computer store and buy a power supply, install it and you should be up and running.

that is if you didn't fry everything from running it without the proper cooling.

make sure that you have proper cooling fans in your computer, a fan outside will not do it.
It sounds like your power supply fan stopped working and it just got to hot and died

Gateway Gt 5220 computer powers on but will not boot


It's either the video card, memory, or motherboard.

I had the same problem with one of my desktop's. It ended up being the motherboard. Had to turn the computer on and off, on and off until eventually it would power on.

I'd start with reseating the memory and video card. Is your video onboard?

Let me know what happens and I'll keep throwing ideas your way.

Best of luck!
