Which fan/heatsinks can be used on an MS-7174 Ver 1 motherboard? It seems there needs to be clearance for some capacitors to fit beneath it.


Heatsinks are dependent on the type of processor that you have, I recommend that you call Microcenter or fry electronic

Really?

Old Intel Pentium 4 processor, that uses a LGA 775 processor socket, worked, but the Intel Core2 Duo 2.2GHz didn't?

This would suggest a bad CPU.
(Central Processing Unit. Another term used is Microprocessor, or simply Processor, for short)

If you hadn't stated using an old Pentium 4 for a test, I would have stated the problem is the Power Supply, or Electrolytic Capacitors on the motherboard.

Capacitors on the motherboard are used as Filters, or Voltage Regulators.

The one's used as voltage regulators, are in the motherboard voltage regulator circuit,

http://www.hardwaresecrets.com/article/616

Part of what the motherboard voltage regulator circuit does, is to regulate voltage for the Processor.

The Processor MUST have a steady, 'clean', supply of voltage, and it MUST be within the tolerance range for the Processor.

Let's look at an Intel Core2 Duo 2.2Ghz processor;
The Intel Core2 Duo E4500,

http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors#.22Allendale.22.2C_.22Conroe.22_.2865_nm.29

The voltage tolerance range is 0.85 Volts to 1.5 Volts. (DC)

Now let's look at an older Intel Pentium 4 processor, that uses an LGA 775 processor socket, and is rated at a maximum frequency rate of 2.66GHz, (Model 505),

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_.2890.C2.A0nm.29

Voltage range is 1.25 to 1.388 Volts. (DC)

IF, the Electrolytic Capacitors were failing in the motherboard voltage regulator circuit, that regulates voltage to the Processor; you would think the voltage regulator circuit would support the Core2 Duo, before it would support the older Pentium 4.

However you may want to closely inspect the Electrolytic Capacitors surrounding the processor socket.

These are NOT the only capacitors in the circuit, that regulate voltage for the Processor.

If you read the article from Hardwaresecrets, you will see how to find all of them.

This is what happens, when Electrolytic Capacitors in the motherboard voltage regulator circuit, (For the Processor), go bad,

http://www.youtube.com/watch?v=KN6_-8fYHo0

(Starts at 0:04)

Due to an Electrolytic Capacitor has a chemical composition inside, (Electrolytic Paste), it can break down over time, and still work in a weakened state.

Eventually it fails.

To explain;

The Electrolytic Capacitors used on the GigaByte GA-945GCMX-S2 motherboard, are Radial Aluminum Electrolytic Capacitors.

http://www.newegg.com/Product/Product.aspx?Item=N82E16813128058

Radial meaning both leads come out of the bottom.
Aluminum designates what the case is made of, and the metal strips inside.

Example of a basic Radial Aluminum Electrolytic Capacitor,

http://en.wikipedia.org/wiki/File:Capacitors_electrolytic.jpg

The bottom example with a blue plastic sleeve, is the Radial design.
The top example is an Axial design. The leads come out of both ends.

In the example above there is a blue plastic sleeve, over an aluminum case. The case resembles a 'Coke-Cola- can with the top, and bottom removed.

The top is a thin flat round disk. It has a shape etched partway into it.
The shape is usually an X, or a lK.

The bottom is called a Bung. It is a synthetic rubber flat round disk.
The leads coming from the metal strips inside, poke through it.

Inside the case are 3 strips.
A) One is a thin, aluminum 'foil'. It is the Conducting Strip, and the Positive lead is connected to it.

B) One is a thin, aluminum 'foil', and has a non-conducting medium applied to it. It is the Non-Conducting Strip, and has the Negative lead connected to it.

C) The last strip is a paper-like substance, and is soaked with Electrolytic Paste.

The paper-like strip is laid in-between the two metal strips, and all three strips are rolled up tightly.

When the capacitor starts to fail, the Electrolytic Paste inside starts to develop a gas. Hydrogen gas.
The gas expands, and pushes against the seals of the case.

(Top disk, and synthetic rubber Bung)

The top disk's X, or lK will split open, and paste will slowly ooze out.
Or the rubber Bung will have one edge poked out of the case, and paste will slowly ooze out.

OR both.

So much paste loss, and the capacitor operates at a weakened state.
TOO much paste loss, and the capacitor fails.

(A Capacitor is designed to slowly build up a charge, then release it all at once.
Crude comparison, is a large swimming pool slowly filled by a garden hose, then one wall of the pool is taken down all at once.

Some cameras use capacitors for the flash unit )

It isn't so much that the computer isn't giving a display.
The reason for no display, is that the computer isn't working, in order to send out a video signal. (No Signal)

Computer will not boot to windows. the screen displays phoenix - awardbios v6.oopg, an energy star ally copyright(c) 1984-2004, phoenix tehcnologies, ltd p4m800-m7 (pm48m309 bf) main processor: intel(r)...


The light you're referring to is the HDD Activity Lamp.
(HarDDrive)

It blinks green when it's operating, and orange for inactivity, or not operating.

You're getting to the BIOS Post screen, but BIOS is handing over the computer to the Operating System.
(Windows XP is an example of an O/S)

When you press the Power On button;

1) A temporary connection is made from the motherboard to the power supply. A 5 volt circuit is made. This turns the power supply on. (Soft Power On)

2) The BIOS chipset, is the first chipset to receive power. (Chipset is a slang term for IC. Integrated Circuit)

The BIOS program, ( 64MB in size), looks to see what all devices are connected.
(Harddrive, optical drives, mouse, keyboard, etc.)

3) Then BIOS does a Ram Memory count,

4) Turns the Processor on,

5) Then hands the computer over to the Operating System.

It looks like BIOS has recognized your Intel Pentium 4 processor, (2.66GHz frequency rate, 533MHz FSB), but hasn't turned the processor on.

[Let me stop,and explain something real quick.
Where you see -
Intel (r) Pentium (r) 4 cpu 2.66ghz (133x20.0)

The r stands for Registered. Intel and Pentium are registered trademarks of Intel Corporation.

It's a Pentium 4 model.

2.66GigaHertz is the Frequency Rate. Slang term for frequency rate is 'Speed'.
Giga = Approximately 1 Billion
Hertz stands for Cycles per Second.

At maximum capacity, your Pentium 4 processor can operate, at a 2.66 Billion Cycles per Second frequency rate.

133 stands for 133Mhz. 133 MegaHertz.
Mega = Approximately 1 Million

This is the Clock Rate. Intel processors are 'Quad-Pumped', so the FSB is actually 533MHz.
(FSB = Front Side Bus)

The 20.0 is the multiplier.
20 times 133Mhz = 2600 Mhz,
or 2.66GHz ]

Now, why is the processor not turning on?

Suspect the Power Supply.
Not enough power to turn the Processor on.

1.ALL the lights for your computer use less than 1 Watt.
2.EACH fan uses 2 to 3 Watts.

3.A typical processor uses 55 to 125 Watts!

(The Processor hasn't been turned on, so nothing else is receiving power yet)

This is the basic specifications for your processor,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_.2890.C2.A0nm.29

Scroll down the left column of the list.
Where you see Pentium 4 505, Pentium 4 505J, and Pentium 4 506. Your processor is one of these three.

Scroll across. You will see 2667 MHz. 2667Mhz is rounded off to 2660 MHz, or 2.66GHz.

You will see 533M/T as you scroll across.
M/T stands for MegaTransfers. A more accurate description of FSB. Front Side Bus.

Scroll further across. You will see 20x. This is the Multiplier. (Look up)

Lastly scroll across a little further. You will see 84W.
This stands for 84 Watts.
Your processor operating at maximum load, uses 84 watts.

Why do I suspect the power supply?
Because it's the number 1 thing to fail in a computer.

Electrolytic Capacitors fail inside, or are failing.
They have Electrolytic Paste inside them.
The paste has developed a gas, (Hydrogen gas), and has popped seals for the capacitor's case.

This results in Electrolytic Paste slowly oozing out of the capacitor, and resulting in the capacitor failing, or has failed.

Electrolytic Capacitors are used as Filters in a computer power supply. They filter the incoming AC electricity from your house, and the outgoing DC electricity made from the power supply.

When capacitors are failing, or have failed, they create a bad power rail.

There are three main power rails in a computer power supply.
1) The 3.3 Volt power rail
2) The 5 Volt power rail
3) The 12 Volt power rail.

With a weak power rail due to failing capacitors, or a bad power rail due to failed capacitors, you do not have enough power to turn the processor on.

Solution?

Use a known, good, compatible power supply for a test. If the power supply is found to be bad, replace it.

Pentium D problem


Hi oilian,
Be glad it did shut down. If it didn't, your new CPU could haveover heated. There are a few reasons for a CPU to over heat.
1.) There is no thermal grease or too little on the heat-sink assembly.
2.) The old thermal grease was not removed or the old thermal tape was not removed.
3.) The heat-sink assembly was not cleaned completely with alcohol before applying new thermal grease.
4.) The CPU fan is running too slowly.
5.) The heat-sink fins are possibly filled with dust build-up & the CPU fan can not cool the heat-sink assembly. Boot to the bios & go to Hardware Monitor. There you can check voltage, CPU fan speed, CPU temp & other bios monitored settings.

Good luck oilian!

CPU fan


When you say power is going to the mobo, are
other fans and lights turning on? You also may have forgotten to plug in
the large ATX power cord from the PSU, or the smaller 4-pin rectangular 12V
power cord. Is the correct local voltage setting for your PSU selected (110
or 220)?
