A Computer Motherboard Diagram Motherboard diagram - motherboard-diagram-01.jpg Once you know what you are looking at, you can recognize the components on any motherboard layout. A computer motherboard diagram is very useful for when you need to replace motherboard, do motherboard upgrades, troubleshoot motherboard, or build your own computer.

  1. PCI Slot - This board has 2 PCI slots. These can be used for components such as Ethernet cards, sound cards, and modems.
  2. PCI-E 16x Slot - There are 2 of them on this motherboard diagram, both are blue. These are used for your graphics card. With two of them onboard, you can run 2 graphics cards in SLI. You would only need this if you are a gamer, or working with high end video / graphics editing. These are the 16x speed versions, which are currently the fastest.
  3. PCI-E 1x Slot - Single slot - In the PCIe 1.x generation, each lane (1x) carries 250 MB/s compared to 133 MB/s for the PCI slots. These can be used for expansion cards such as Sound Cards, or Ethernet Cards.
  4. Northbridge - This is the Northbridge for this motherboard. This allows communication between the CPU and the system memory and PCI-E slots.
  5. ATX 12V 2X and 4 Pin Power Connection Power Connection - This is one of two power connections that supply power to the motherboard. This connection will come from your Power Supply.
  6. CPU-Fan Connection - This is where your CPU fan will connect. Using this connection over one from your power supply will allow the motherboard to control the speed of your fan, based on the CPU temperature.
  7. Socket - This is where your CPU will plug in. The orange bracket that is surrounding it is used for high end heat sinks. It helps to support the weight of the heat sink.
  8. Memory Slots - These are the slots for your RAM. Most boards will have 4 slots, but some will only have 2. The color coding you see on the motherboard diagram is used to match up RAM for Dual-Channel. Using them this way will give your memory a speed boost.
  9. ATX Power Connector - This is the second of two power connections. This is the main power connection for the motherboard, and comes from the Power Supply.
  10. IDE Connection - The IDE (Integrated Drive Electronics) is the connection for your hard drive or CD / DVD drive. Most drives today come with SATA connections, so you may not use this.
  11. Southbridge - This is the controller for components such as the PCI slots, onboard audio, and USB connections.
  12. SATA Connections - These are 4 of the 6 SATA connections on the motherboard. These will be used for hard drives, and CD / DVD drives.
  13. Front Panel Connections - this is where you will hook in the connections from your case. These are mostly the different lights on your case, such as power on, hard drive activity etc.
  14. FDD Connection - The FDD is the Floppy Disk controller. If you have a floppy disk drive in your computer, this is where you will hook it up.
  15. External USB Connections - This is where you will plug in external USB connections for your case or USB bracket.
  16. CMOS battery - This is the motherboard's battery. This is used to allow the CMOS to keep its settings.

Where to find manual for motherboard 143159 imperial Gv 20030812?


Good luck. Used to be you could get a mobo manual from e4allupgraders.

The Imperial board is made by TriGem
Started out as TriGem Sambo, is now TG Sambo

The Imperial models were Imperial G, Imperial GL, Imperial GV, and Imperial GLVE, if memory serves.

TriGem Imperial GV - 143159 -20030812

http://www.ebay.com/itm/gateway-emachine-mother-board-imperial-gv-20030812-/111025938736?pt=Motherboards&hash=item19d9a96130

Bad photo, but it does have the mouse Zoom In feature.

CMOS jumper and Clear BIOS Password jumper, down by the Front Panel header; is the same as used on the TriGem Imperial GLVE -129504,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07540&lc=en&cc=us&product=83481

Scroll down to Motherboard Layout (Illustration), and Photo; then down to jumper info.

(By the way.........the BIOS chipset is removable, therefore replaceable)

The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to; is the Front Panel header.

This is PANEL in the illustration. Bottom/Right corner. Uses the same Front Panel pinout, as your Imperial GV uses.

8 pins along in a row.
Starting on the LEFT side going towards the Right;
Pins 1, 2, 3, NO pin 4, 5, 6, 7, and 8.

A) Pin 1 is N/C. Not Connected
(May not even be there for all I know)

B) Pins 2 and 3 are for the Power On LED.
Pin 3 is for the Positive wire.
If the PWR LED is dim when the computer is on, switch the wires around.

C) There is NO Pin 4. At least that is what I make, looking at the Front Panel header pinout. Indicate Pin 1 is N/C, and Pin 4 is N/C.

D) Pins 5 and 6 are for the HarDDrive activity LED light.
Pin 5 is for the Positive ( + ) wire.
If the HDD LED is dim when the Harddrive is active, switch the wires around.

E) Pins 7 and 8 are for the Power On switch.

HOWEVER, since the motherboard photo on HP Support, and Ebay; is as clear as mud; suggest you do this,

Connect your Power On switch to Pins 7 and 8;
OR,
touch across them briefly with a small flat tip screwdriver.
(Power plugged in)

See if that is correct for the Power On switch. What will happen if it isn't? Nothing. Pressing the Power On button just won't turn the computer on; is all.

Turned the Power Supply (Computer) on?
Good. We can assume the rest of the pinout is correct also.
Want to make sure? Easy.

Take an LED bulb (Power On, or HDD), and touch it's two wires to the Power On LED pins, in the Front panel header.
Stays on? Yep. Power On LED pins.

Blinks? Whoops.
Those are the Harddrive activity LED pins.
Just that easy to check it. With using an LED, you won't harm anything even if the pinout is wrong.

Moving on.........

Using the HP Support page, for that TriGem Imperial GLVE motherboard, the Motherboard Layout is the same as the Imperial GV.
(So is photo, 'natch)

Referring to the layout, and photo;

A) Power cables:
Two
20-pin ATX main power cable, and 4-pin ATX +12 Volt power cable.

General example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Note* Color of power cable connector does NOT matter.
Can be Whitish, Yellowish, Black, Sea Foam Blue, or Lactating Mammary Gland Pink. (Made the last two up)

Goes to the motherboard connector immediately above PCI slot 1.
Note the LOCK on the side of the power cable, and corresponding TAB on the motherboard connector.

General example of 4-pin ATX +12 Volt power cable, and connector on motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Power for the Processor
Looking at the motherboard illustration, look at the Northbridge chip; -> Intel 845GL in the middle.

ATX 12V to the left, is where the 4-pin ATX +12 Volt power cable plugs in.
See the aluminum finned Heatsink, sitting on the Northbridge chip?
The whitish/yellowish 4-socket hole square connector, to the Left.

Moving on............

See where it states Primary IDE to the bottom/right in the illustration? Blue IDE connector?
That is where the Harddrive plugs in.

This is a general example of the connector,

http://en.wikipedia.org/wiki/File:PATA-cable.jpg

Note the Locating Lug on the top/middle. This particular style uses two ribs. Some are just a solid block.

The reason I brought it up, is if there is NO Locating Lug on the connector; let me know in a Comment.
I'll tell you how to use the faint Red stripe, on the side of the flat cable; in order to plug it in correctly.

The optical drive (CD/DVD drive) plugs into Secondary IDE.
You can see where a Floppy Drive plugs in.

Above the Processor (CPU) socket to the Right, is where a computer case fan plugs in. PS_FAN.
To the upper Left, is where the Processor fan plugs in.
CPU_FAN

To the left of the ATX Power Connector, (20-pin ATX main power cable; motherboard connector), is the connector for the small audio cable; coming from the optical drive. (CD/DVD drive)

Optical Drive In.

Right next to the round CMOS battery, is the Front Panel USB header.
-> TWO USB ports connect to this header.
(USB)

A 4-pin Peripheral power cable is used for the Harddrive, and Optical Drive.
Misnomered as 'Molex' power cable,

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

Note the rounded corners. When plugging the power cable in, these rounded corners always go UP.

[Molex was the first maker of the power cable connector.
The name stuck.
Kind of like calling an adjustable open-end wrench a 'Crescent wrench' ]

The motherboard chipset is an Intel 845GV.
This is what Processors (CPU), and Ram Memory are supported,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

Single-Core processors.
Use a Socket 478 processor socket.
Intel Pentium 4, Celeron, or Celeron D.
(Celeron D is NOT a dual core processor)

400 to 533MegaHertz Front Side Bus processor support.
(400/533MHz FSB)

DDR Sdram ram memory that is either 266MegaHertz, or 333MHz.
(PC2100 and PC2700, respectively)

2GB's of it.
1GB for EACH ram memory slot.

Emachine t2824 board diagram


Here is the diagram that shows you how to hook up the wires:

http://www.fixya.com/uploads/images/284ECAC.png

If you still have no video then reseat the memory one stick at a time in one slot at a time.

If you still have no video then reseat the cpu into its slot.

If still no luck try a different stick of RAM by trying it one slot a time.

Last step, unhook the power connectors from your device so the only power connectors that are connected are the power to the motherboard and the p4 connector to the motheboard. Also make sure your power supply is set to 115v. Its the red switch on the back of the power supply.

If none of this works, then the motherboard is bad. Hope this information helps.
