Question about Intel D865GVHZ Motherboard

Emachines t3882 wont power on

It has one green light illuminating on the mother board. has power on the green and purple wires at the 20 pin mother board connector at 5v each. I assume the yellow and/or red wires that connect to everything from the power supply are supposed to have some voltage on them when plugged in but they do not. The fuse is good in the power supply case but i assume it could still be faulty. thanks

The yellow wire carry 12 volt while the red one is 5 volt. But to check the voltage you have to unplugged all the four wires connectors (yelow, black, black red) and measure them one by one. If you say that they don't have any voltage on them then you have a faulty power supply. Replace it to solve the problem.
But if during unplugged your have the correct voltage read then it could be one of your device faulty. Normally your CD-ROM drive or floppy drive or HDD.

No lights turn on, game doesn't turn on. Appears Dead..

If this is in a computer and the computer does nothing at all when you push the power button you might want to check the power supply. This can be manually done on an ATX power supply both 20 and 24 pin connections. First you remove the main system power cable from the mother board " big rectangle one " and locate the green wire. After you have found it use a paper clip bent in a U and touch the green wire and ANY black wire " all blacks are ground " This will turn on a power supply if its good. If your power supply fails to start i would look into buying a new one.

Good day sir, let try to test first the power supply, Unplug the power cord, remove the 20 pin (24 pin for the late model) molex power connector from the motherboard, plug in the power cord, get a 2 to 4 inch jumper wire, short the green wire with any of the red or black wire on the molex 20 pin power plug, the result maybe the following:
  1. you will see the power supply fan turn. you power supply is in good order. replug the power supply, and test again.
  2. you will see the fan turn for a few second then stops. you power supply is selective, and may require a different type of motherboard. Get a new one.
  3. you wont see the fan turn at all. get a new one.
If in case you are with #1. uinplug the power cord and remove all the expansion cards, data cables from the hard disk and cd drives. we are trying to isolate the problem. make sure that the only connected cables on the motherboard are as follows:
  1. 20 pin power cable.
  2. 4 pin 12 volt power cable (if applicable)
  3. speaker
  4. power switch
  5. power led
Test the pc once more. plug in the PC. If still the board wont power on. problem with your motherboard. Note:make sure your RAM is good. Hope this helps.

How do Iplug the power switch wires in the corect place on the mother board? for the emachine T2824


Did you try to open your CPU casing to find the socket in your motherboard witch is totally fix with the power switch wire. The power switch wire are two forms, there is a 20 pins and 24 pins. If your power switch socket is only a 20 pins, you need to put only the 20 pins.

The 24 pins is not totally combined in power switch wire. If your motherboard power socket contains only 20 pins, so remove the 4 pins in your power switch wires. "Good luck!!"

Hope it may helpful for you!

Wont load up

If everything is working properly, then yes, those lights are normal. Many motherboards have LEDs on them to show standby power. You probably didn't notice them until you worked on the thing.

MY Intel mother board D845WN can't boot

Try swapping those three connector plugs around from the front panel led lights to the other pins on the 9 pins connector, 5 in a row and 4 pins at the bottom. The bigger plug with 3 holes but only two wire will definitely go on the 5 pins row.

Swapped mother board

Hi Paul,
see page 8 number 15 for location. Than see page 19, System Panel Header in your manual.
The basic wire color's for positive are red, blue, green & can also be light blue, light green, light red.
Negative wires are usually white or black. Case wire colors do vary from case to case.
To see pin one shown on page 19, (positive + for hard drive led = HDLED+). Bottom row farthest pin to the left of set. Pin two is above pin one. Pin two is, PLED+ (known as power led). Pin 3 is to the right of pin one & is HDLED- (Hard drive led, negative). Pin 4 is above pin 3 & is also PLED-, (Negative for power led). ECT!
6781222.jpg If your new case has an internal speaker (Used for P.O.S.T, power on self test). This would connect to, Chassis Speaker Header located on page 8, number 16. Again, normally only two wires are used across the 4-pin connector. (One at each end of the connector).

To see ASRock's main site for the 775VM800 motherboard click this link:

Good luck Paul!
Run into a snag, just post the issue here.

Intel emachine t3828

Geeze, after working on hardware for 27 years i love the short circut dummie. Anyway yes, it's the motherboard / yes the green light will still come on on that model and quite a few other models. Dont worry about repairing / i.e. removing components on the motherboard, it's a fruitless endevor but a great way to waste time. A motherboard for that model will cost about 100-150 bucks / easy replacement. It's actually rare for both the power supply and mother board to go out on a tower/mini tower type system. Older laptops had that type of prob. Those emachines were **** for the mostet part. On the other hand Gateway has really gone up in quality and i have been quite impressed with them in the last few years...

Motherboard taken out by eMachines Bestec power supply

I have not identified the specific components on the motherboard that blow, but I can tell you the defect in the Bestec supply. The +5 VSB, which is the voltage that is on at all times, loses regulation and climbs to 8-11 volts. I believe this "higher than the required" +5V takes out the components on the motherboard involved with the computer/power supply "turn-on" circuitry. The "on" button on the eMachines front panel no longer turns the motherboard on because the "kept alive when the main power is off circuits" - which allow the on/off button to do its job of turning on the machine - no longer work.
Test your Bestec power supply by plugging it in the wall socket and have it not connected to anything. Read the voltage between the purple wire and any black wire. If you see +5.0V, then this wasn't your problem. If, like it did on mine, is closer to between 8, and 11 V, this is what took out the motherboard.
