Asrock conroe b65gv motherboard only working cpu fan.....


First thing to check with a desktop computer problem is the Power Supply.
This I state a lot.
In reality there's a flaw.........

In reality a person should visual check for bad capacitors on the motherboard, then move to the Power Supply.

The AsRock Conroe865GV uses nothing but Electrolytic Capacitors.
(Radial Aluminum Electrolytic Capacitors to be exact)
Doesn't use any Solid Polymer Capacitors.

These are known to be a 'weak link' on a motherboard.

http://capacitorlab.com/visible-failures/index.htm

http://www.youtube.com/watch?v=Lut7MX5Dd_A

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

The ones used as voltage regulators are in the Motherboard Voltage Regulator Circuit,

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

Just thought you might like to know

Since you indicate the CPU fan is spinning, I assume you know the computer isn't supposed to be dirty inside.
If you don't............we need to have a long talk..........

With a Power Supply having a weak voltage power rail, you may see LED's light, and maybe fan's spin, but there won't be enough power to turn the CPU (Processor) on.

1) If ALL of the LED's were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical CPU (Processor) can use 51 to 130 Watts. Just depends on what CPU it is.

AsRock Conroe865GV?

http://www.asrock.com/MB/overview.asp?Model=ConRoe865GV

The motherboard chipset is an Intel 865GV chipset,

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

Can support Intel Pentium 4 HT, models 620 through 672; for ->one.
They can use Up To 115 Watts,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_2M_.2890.C2.A0nm.29

[ AsRock Support states the Conroe865GV will support Intel Core 2 processors, but I don't believe it.

It isn't until you get to the Intel 945G, that Core2 support is picked up.
Just my 2 cents ]

High voltage AC electricity comes into the Power Supply, and is contained in it's metal case.
The AC voltage is converted into low DC Voltages.

3.3 Volts DC, 5 Volts DC, and 12 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.

A multimeter is used to check the three voltages.
Need guidance with this post back in a Comment.

[An economical multimeter around here, can be purchased for around $5 to $12.
Available in a lot of stores. I have seen them on checkout aisle racks, of major discount stores ]

OR;
Use a KNOWN to be good, Compatible power supply for a test unit.
May be a working computer that is not being used, that you can Temporarily borrow it's power supply.

Let's start the diagnosis from here..........

Msi 6378 turns on but I don't see anything on the monitor


Not trying to be trite sir, but I think that is a broad unsupported statement........

If we look at the known universe...........

!O_O! What a minute?...........What?............Oh........



...fans, video card, cpu, ram, cd drive, hard drive, and power supply work; (Semi-Colon), as well as the motherboard itself...........

With all due respect what do you base all that diatribe on?

Fans spin, and LED's light up; and you're going to assume the other hardware components, must be working as well?

THAT, is your basis for your hypothesis?

A) You can see the fans spin......

B) You might hear the harddrive spinning it's platters, while it is in an endless loop............

C) You can press the optical drive's (CD/DVD drive) tray release button, and open the tray.......(To assume it's getting power)

But tell me how you assume the cpu, motherboard, ram memory, graphics (video) card, and Power Supply; to be good?

What do you base this assumption on?

With all due respect..............nothing.

Your observations are baseless.


Seem like I'm trying to be rude?

No sir. Trying to get you to think outside the box



What is the common 'denominator' here?

What hardware component is common to all the others?
That........if not working at full capacity, would not allow the others to work?

The motherboard is the 'Building Block' of a computer.
The CPU is the 'Brain'
The Power Supply is the 'Heart'.

No 'heart' you have nothing.

When diagnosing desktop computer failure, the first hardware component to diagnose; is the Power Supply.
Without it operating at full capacity nothing else works.

Past this point the diagnosis can go on. (Power Supply deemed to be good)
If not you will be pulling your hair out searching for answers.

Primer:

1) If ALL of the LED's were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical CPU (Processor) can use 51 to 130 Watts of power.

A Power Supply with a weak voltage power rail, will have power to light those simpy LED's, and maybe spin fans; but will not have enough power to turn the CPU -> ON.

Have an economical multimeter?
They range in cost from $5 to $12, usually.
I have seen them on checkout aisle racks, at major discount stores.
Auto parts stores have them, but usually more expensive.

With it you can test the 3 main DC Voltages, coming out of the Power Supply;
3.3 Volts
5 Volts
12 Volts

Again, all are DC Voltage.
In comparison two D cell flashlight batteries produce 3 Volts DC.
(The dangerous AC voltage is kept contained, in the metal case of the Power Supply)

OR,
Use a KNOWN to be good, Compatible power supply for a test unit.

("I need to borrow the Power Supply out of your computer honey.
No, no.......I'll put it back. This shouldn't take long.
What? Touch it, and I'll lose sum fingers?" )

Also, follow Anti-Static Procedures, and look at the Electrolytic Capacitors on the motherboard.
In fact, what the hey right? Might as well look at them first,

A) http://capacitorlab.com/visible-failures/index.htm

B) http://www.youtube.com/watch?v=Lut7MX5Dd_A

Capacitors on the motherboard are used as Filters, or Voltage Regulators.
The ones used as voltage regulators are in the
Motherboard Voltage Regulator Circuit.

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

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

Too little, or too much, and it turns off. (BIOS turns it off)

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

(For older motherboards, and to include older server computer motherboards; voltage regulation for the processor was accomplished with a VRM. Voltage Regulator Module.
A separate, replaceable 'card' )

No Video when the system is turned on


Doesn't quite work that way, and good job on capacitor replacement

!O_O!

What bites is sometimes the Electrolytic Paste dries up, and there is no visual signs of failure.

1) Think I better tell you about the motherboard voltage regulator circuit;

One of the things the motherboard voltage regulator circuit does, is to regulate voltage for the Processor. (CPU)

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

Cannot be too much, or too little; or BIOS turns it off.

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

General thinking would be that the Capacitors that surround the Processor, are the only ones for it.
This is a fallacy.

There could a capacitor, or capacitors; that are in the motherboard voltage regulator circuit, and for the Processor; and are NO where near the Processor.

You actually have to follow the circuit traces, and see.
Example; Is there a capacitor over by the Ram Memory, or another outlying area, that a circuit trace from it leads to the processor socket?

Read the Hardwaresecrets article, and I believe it will help with understanding.

2) Don't know your soldering prowess, not knocking it.
You don't have any cold solder joints, do you?
That will make you pull your hair out, until you find it.

3) The Power Supply thing; the statement that it doesn't work that way;

You could have a Power Supply with a weak voltage power rail.
LED's would light up, and fans may spin; but there isn't enough power to turn the Processor on.

1) If ALL of the LED's were lit up at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor (CPU) can use 51 to 125 Watts of power.
Just depends on what Processor it is.

When testing; the Processor, processor fan and heatsink, plus ram memory is installed.

You are trying to get the BIOS Setup screen to come up.

Make SURE there is a stick of ram memory in Slot 1. (DIMM 1)
This is the ram memory slot that is closest to the Processor.
The Processor reads Slot 1 first.


Yes. If you have more than 1 ram memory module ('Stick'), trade them around/out, and see if you have a bad ram memory module.

Also suggest clean the gold plated contact pins, on the Ram Memory module; with a pencil eraser.
Use air to remove the eraser dust.

When diagnosing a desktop computer problem, POWER is ALWAYS checked first.
Then see if computer is dirty inside, and then clean ram memory module's, gold plated contact pins with pencil eraser.

If you are not following, or if the person before you was not following; Anti-Static Procedures, use the motherboards for a Frisbee, or expensive paperweight.

Regressing;
There are 3 main voltage power rails;
A) 3.3 Volts
B) 5 Volts
C) 12 Volts
ALL are DC Voltage

In comparison two D cell flashlight batteries produce 3 Volts DC.

A) ALL Orange wires are 3.3 Volts
B) ALL Red wires are 5 Volts
C) ALL Yellow wires are 12 Volts.

ALL Black wires are Ground wires.

Voltage power rail.
ALL Orange wires are 3.3 Volts, and they all end in one central point; inside the power supply; the 3.3 Volt power rail.

Same thing for Red 5 Volt wires, and Yellow 12 Volt wires.

Multimeter red probe lead (Positive) plugged into Red hole on multimeter, that has DCV next to it. DC Voltage.

Function knob set to DC Voltage (DCV)
If just a symbol, the symbol is a dotted line over a solid line.
(Curved line over solid line is ACV. AC Voltage)

If more than one scale, set to 0-50 volt scale, DCV.
0 to 50 volts Direct Current Voltage. (DC Voltage)

Positive (Red) probe lead of multimeter TO power wires.
3.3 Volt (Orange), 5 Volt (Red), 12 Volt (Yellow)

Negative (Black) probe lead of multimeter TO Ground wire.
ALL Black wires are Ground wires.
Read multimeter.
(Power supply on)

You can purchase an economical multimeter, for as little as $5 to $12.
Auto parts stores have them. (A little more pricey usually)
I have seen them on checkout aisle racks, at major discount stores.

No?
Not feasible?
Is there a working computer you can TEMPORARILY, borrow it's Power Supply?
KNOWN to be working, and Compatible Power Supply?
Use for a test unit. See if the Power Supply is the problem.

Not to be a hater, but I would use SuperMicro motherboards; to skip across the lake with.

"Wow! Look at that baby go!"

But DON'T! It's bad on the environment.
(Fish get two heads, and stuff.


NO! Not really. You gonna' believe that? lol!

It IS bad for the environment, however)

MY ASUS P6T DELUXE TURNS ON BUT THE C-MOS SCREEN DOESNT SHOW.....


First thing to check with a desktop computer problem, is the Power Supply.

No sir,....cannot ASSUME power supply is good, because LED's light up, and fans spin.

1) If ALL the LED's were lit up at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor (CPU) can use 51 to 125 Watts of power.
Just depends on what Processor it is.

Intel Core i7, model 950?

http://en.wikipedia.org/wiki/List_of_Intel_Core_i7_microprocessors#.22Bloomfield.22_.2845_nm.29

Up To 130 Watts. (TDP. Thermal Design Power, or Thermal Design Point. Whichever you prefer )

Exceeded the spec's I stated.

Power Supply with a weak voltage rail, will have enough power to turn the wimpy little LED's on, and spin fans; but will NOT have enough power to turn the Processor on.

How to know?

Test the 3 main voltages coming out of the Power Supply, with a multimeter set to DC Voltage;

Or,

Temporarily substitute the Power Supply, with a KNOWN to be good, Compatible one.

Borrow from a working computer. Then you can diagnose if this is the problem; and can put it back in the working computer.

The motherboard you have needs at least 150 Watts.
CPU = 130 Watts
Each ram memory module = 15 Watts (DDR3 Sdram)
Harddrive and optical drives around 25 Watts each.
Fans 2 to 3 Watts each.

Your CPU requires 3 ram memory modules at least. 6 can be used.
So........
150 + 130 + 45 + 50 + 6 = 381 Watts.

Bare minimum is 400 Watts, and you should have a 500 Watt power supply. Need at least 10 percent over what is needed; but why play around? 500 Watts.

(Your SMPS is of the ATX technology)

Need guidance in performing this? Post back in a Comment.

Also:
When checking a desktop computer, after checking power; and this does no good;

Have ONLY the Processor, processor fan hooked up, and Ram Memory.
That means disconnect EVERYTHING else.

Harddrive, (Power and data cable), optical drive, (Power and data cable), computer case fans, (NOT processor), Card Reader cables, Front Panel USB cables, etc.

All you are trying to do at this point, is see if you can pull the BIOS Setup screen up.
If so then add Harddrive, and computer case fans.

[ Note* This is a fast test. BIOS Setup screen comes up, turn the computer off.
CTRL key, ALT key, and Delete key AT SAME TIME.

You don't want to overheat the motherboard. Primarily the Northbridge chip, and Southbridge chip; of the motherboard chipset.

You're just performing a fairly fast test ]

Intel Core i7 requires THREE ram memory modules, at least.
People have used two, but do not apparently understand the Nehalem technology, and using an Intel Core i7.

hi,


if you dont have any beeps

the mother board usually damaged , but for assurance , do the follow:

1- chek the power and see all of the cables inserted correctly and spcially check the voltages
of 12 v and 5 v by connecting the volt meter :black cable of one of socket of power to ground
cable of volt meter and one time connect the other cable of volt meter to red cable of power
socket which should be 5 v and other time connect to yello cable of socket power which should
be shown 12v .
if ok ,
2- chek the ram or rams may be inserted incorrectly.
3- check the graphic card may be inserted incorrectly.
4- check the capacitors around the CPU may be swollen.
if you did noy any problems , you must refer to a technician or gaurantee .


good luck
