Long POST and will not mount HDD.

what is the problem, Dr?

Pin Configuration = Pinout

The Front plastic panel of the computer is the Front Panel.
The area of pins on the motherboard that the cables (Wires) go to, is the Front Panel header.
Front Panel header pinout.

The motherboard used in an eMachines T2672 desktop computer is an FIC AU31 motherboard.
Made by First International Computers (Inc.) for eMachines.

http://www.e4allupgraders.info/dir1/motherboards/socketa/au31.shtml

Orient the motherboard like it is in the photo, so we are both looking at it in the same direction.
{Processor to the top, Ram memory slots to the right, white PCI slots to the bottom. The way it sits in the computer case}

The Front Panel header, is a small black rectangular block that sits horizontally, at the far right bottom corner.

It has two rows of pins.
4 across the top, and 5 across the bottom.

(The small rectangular block above it, is for connecting a Power On LED light that has 3 wires. More on this in a moment)

The pins are numbered.
The pins are numbered Evenly across the top, and Odd across the bottom.

Starting from the Left side going across to the Right, on the Top row;
Pins 2, 4, 6, and 8.
There is No Pin 10.

Starting from the Left side going across to the Right, on the Bottom row;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED light. (HDD LED)
Pin 1 is for the Positive wire ( + )
(If the LED light is dim when operating, switch the wires around)

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used. (Reset button)

C) Pin 9 is Not Used. (NC. No Connection)

D) Pins 2 and 4 are for the Power On LED light, IF it is a 2 wire LED light.
Pin 2 is for the Positive ( + ) wire.
(If the LED light is dim, switch the wires around)

If the Power On LED light has 3 wires:
Use the Power On header above the Front Panel header.
This rectangular block has 3 pins.

Starting from the Left side going to the Right; Pins 1 , 2, and 3.
Pin 1 is for the Positive wire.
Pins 2 and 3 are Ground wires.

E) Pins 6 and 8 are for the Power On switch. (Power On button plastic assembly has an ATX power on switch inside it)

This is a link to a free motherboard manual, for the FIC AU31 motherboard. It is in Zipped file form.
(A Zipped file is a compressed file. It is used for one, to send a large file over the internet)

If you do not know how to unzip a file, post in a Comment, and I'll lead you step by step.

[ P.S.
The motherboard chipset is an Nvidia Crush 18G + MCP AGP
It is an Nvidia Force 2 chipset,

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_chipsets#nForce2

Supports Processors that are AMD, and fit in a Socket A processor socket.
(Socket A is also known as Socket 462)

Supports AMD processors that have either a 200MegaHertz Front Side Bus, or a 266MHz FSB, or a 333MHz FSB.

AMD Athlon XP processors with either a 266MHz FSB, or 333MHz FSB.
From the 1500+ model up to the 2800+ model.

AMD Duron processors with a 200MHz FSB.
From the 800MHz to the 1.3GHz models

(AMD Athlon XP is the top of the line. Then it's Duron, then Sempron.
A Sempron processor has half of the L2 cache that a comparable Athlon XP does)

Ram Memory is DDR Sdram at either 200MHz, or 266MHz, or 333MHz, or 400MHz.
Depends on the Processor used.

(Ram Memory typically operates at half of the frequency rate ('Speed') that the Processor does.
If the processor's FSB is 333MHz, you can use 400MHz DDR Sdram. {PC3200}

Confusing I know.
DDR Sdram is 'double-pumped'. It is actually 200MHz for PC3200.
This is close to half of 333MHz.

Processor has an FSB of 266MHz? Ram memory used will be 266MHz. Remember, it is actually 133MHz for the ram memory. (PC2100)

Need an AMD Athlon processor?
I found this place years ago. Not advertising for them. Just computer geeks sticking together, and sharing information. (I have bought a motherboard from them, and it works fine),

This is the memory spec for your motherboard...

3 x DDR DIMM Sockets
Max. 3 GB unbuffered PC2100 / PC1600 non-ECC SDRAM Memory (PC3200 Max. to 2 banks only / PC2700 Max to 4 banks only)

Part of the memory spec will tell you if it is single sided (memory chips only on one side of board)
Double sided is memory chips on both sides of the board....Some systems will not work with double sided memory...

Here is what you asked for from memorystock.com

Presario SR1920NX Memory Specifications Standard Memory 512 MB (removable) Maximum Memory 4.0 GB Memory Expansion 4 sockets Memory Comments PC3200 DDR SDRAM DIMMs. Supports Dual Channel DDR. CPU Type 2.2GHz AMD Athlon 64 3500+ Model Comments GeForce 6150 LE ChipsetI recommend Crucial brand memory. Hope this helps:)

Unfortunately you will have to buy an external cd/dvd drive simply because windows xp has no built in recovery partitions you will need the recovery cds to perform a factory recovery.

No for that model you will need PC2700 DDR SDRAM DIMMs Memory Type

Hope it answers your questions.

you can deselect from BIOS - CAS LATENCY TIMER to value 2, or better (2,5)

I should think that will be ok but why restrict it to 512 when you can have 1024 mb

hi, from your reference i could get the info that your pc is running with the mainboard similar to FIC - am37,and with that the below mentioned processors are supported. Recommended Speeds: AMD Athlon? XP 2600+ (266 FSB) AMD Athlon? XP 2400+ (266 FSB) Model 10 w/ 256K Cache AMD Athlon? XP 2400+ (266 FSB) AMD Athlon? XP 2200+ (266 FSB) Model 10 w/ 256K Cache AMD Athlon? XP 2200+ (266 FSB) AMD Athlon? XP 2100+ (266 FSB) Model 8 AMD Athlon? XP 2100+ (266 FSB) Model 6 AMD Athlon? XP 2000+ (266 FSB) Model 8 AMD Athlon? XP 2000+ (266 FSB) Model 6 AMD Athlon? XP 2000+ (266 FSB) Model 10 w/ 256K Cache all the best.. sreejith
