SOURCE: Emachine flashing yellow lights, fans power up when P8 is unplugged

Did some research and found this site which will tell you which pins to test. It is possible also that its not powerful enough for the devices you have. I would try again only giving power to the motherboard pins, of coarse and the hard drive. If works then plug one device at a time.
Good luck

You can test the power button. Remove the wires from the power on pins on the motherboard. Momentarily jump the two pins with a small screwdriver. If the computer starts the power button is bad. If it still doesn't start then something else is wrong. Did you test the memory? Also do all of the fans work, especially the CPU fan? It can't hurt to test with the other PSU. You know the HDD is good. Test one piece of hardware at a time and hopefully you will find the problem.

You should be able to see the words/letters that go with the jumpers on the motherboard itself. look around the jumper settings area for power, pwr etc. and match them up with your jumpers which should have what the go to on them.

Marvelous description, but you can only fit parts that have the same socket on them. As long as you remember that, you will be okay. For CPU and motherboard information (compatibility) try CPU upgrade website and for CPU spec and sockets try CPU world (both run by the same people) very well designed sites and informative. The other stuff comes with experience, although you could try a book such as computers for dummies or buy a magazine such as Micro mart (weekly) as it reviews new and old kit and has a very good help section.

I don't know how to plug in the wires for the ASUS a8n sli deluxe motherboard


Here is the manual for your motherboard (since describing a diagram probably isn't very useful...)
http://dlcdnet.asus.com/pub/ASUS/mb/socket939/A8N-SLI/e2024_a8n-sli.pdf

You want to look at pages 27-35, they describe what you need to plug into the motherboard. Basically make sure you have connected:

1) 24-pin power cable (from power supply)
2) 4-pin power cable (for CPU from power supply)
3) Any case fans with 3/4 pin connectors.
3) hard drives (SATA or IDE)
4) USB front panel ports
5) Audio front panel ports
6) Case plugs (power LED, hdd LED, power switch, and reset switch).

ECS P4IBMS Motherboard CPU Voltage Jumper Settings


I don't believe that there is a P4 motherboard that needs jumper setting to specify the CPU voltage. This used to be common for Pentium & Pentium II motherboards, & some Pentium III motherboards. But I have never seen a Pentium 4 motherboard that require this kind of setting.
Besides, I checked the motherboard's manual & I saw that there is a sub-menu in BIOS labelled "Frequency/Voltage Control". This should be the place where the CPU voltage should be set, & on most motherboards, CPU voltage & frequency are automatically detected.

Model name BLUFORD. E139765 motherboard. I need J16 pin layout for the power switch, reset switch, etc. Dell is not very helpful with this paticular board for some reason. Thank You for any info. DW


This is what I found after extensive searching,

......................O
.PWR LED- O O
.HDD LED- O O HDD LED+
.................... O O
.................... O O
.................... O O PWR LED+
.................... O O
...PWR SW O O PWR SW
.................... O O
.CON CNT O O CON CNT

Looks pretty lame, huh? I found this on Dell's Community Forum.
I gather, this motherboard was used in the Dell Dimension 2350.

http://support.dell.com/support/edocs/systems/dim2350/techov.htm#1101565

Looking, at what Dell has for the layout of the Dimension 2350 motherboard, there are 20 pins in the J16 header, just like he has crudely shown above. I don't see one missing in the corner, though. Of course, the link above is a crude example from Dell.

This person stated it was for the J24 header on the motherboard. Also stated that it was the Front Panel I/O header. (At least that's what was stated) I believe he was confused with the Control Panel header J24. Hopefully it is for the J16 Front Panel I/O header, as it has the Power On switch, HDD activity LED, Power LED, and so on.

Indications are that the O's represent the pins. There was a statement of taking -> Note, that there is a missing pin in the upper corner, and this orients the connector view, Orients, how you are looking at the connector. Only you will know for sure. I don't have this motherboard in front of me. Dell ISN'T giving ANY info out.

This person had the Bluford E139765 motherboard, in a Dell Dimension 2350.

The statement was also made, that there is a Brown jumper wire that connects the two CON CNT pins together, but didn't know if this jumper is required, as this person is putting this motherboard, into an aftermarket computer case. (?)

Solution?
What I would do.
I would have the power supply plugged in. I would use an LED lamp, with two wire leads attached to it. Leads of about two inches long, or more. (Borrow one out of the Front Panel, or from another parts computer?)

Twist the ends of the lead wires tightly. I would then touch the leads to two pins. Should they be power Out pins, (HDD activity lamp pins. Power LED pins, and so on), the light will light up, and not short out the two pins touched.

(If the LED light doesn't light up, no biggie. It just means the wires need to be reversed. Bear this in mind, when you go to hook the LED's up)

When the two pins for the Power On is found, the computer will turn on.

Judging by the crude diagram the missing pin is on the upper right.
Only you will know for sure, as the J16 header should have a flat place in one corner, where a pin would go. NO pin.

If so, this is what I see.

Processor to the left, PCI slots to the right, J16 header on the right, above the PCI slots. The header goes along the edge of the motherboard, lengthwise.

I'll number the pins like this.
Starting at the Top Left, and going down the Left side.
Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.

Starting at the Top Right, and going down the Right side.
NO pin, (Would have been Pin 2),
Pins 4, 6, 8, 10, 12, 14, 16, 18, and 20

Pins 3 and 4 are for the Power LED. (Confusion here)

Pins 5 and 6 are for the harddrive activity LED. PIn 6 is for the + wire/

NO connection to Pins 7, 8, 9, and 10

Pins 11 and 12 are for the Power LED.
(Which ones to use? Pins 11 and 12, or Pins 3 and 4? I leave it up to you to test as the computer is on, and see)

NO connection to Pins 13 and 14

Pins 15 and 16 are for the Power On switch.

NO connection to Pins 17 and 18.

Pins 19 and 20 are for that jumper wire he mentioned. I would try it without it. If the computer doesn't come on, or something doesn't work, like the harddrive for example, I would unplug the computer from power, then attach this jumper. Plug in, and see if everything works.

I recommend that you formatt your HDD to a FAT32 system probably by using another pc then you should also ensure that your bios is setup for the appropriate operating system. maybe just download the appropriate bios files off the gigabyte web site.
