The motherboard does not supply any voltages. This is done by the switch mode power supply. If the 12 volt is below specs then the switch mode power supply is faulty and it needs to be replaced.

The chances are that you have an old motherboard which is not compatable with the new graphic card. Or you may be running windows 98 and are downloading the driver for xp or visa versa. The probable solution, will be to sell the new card on ebay and buy the best old card you can off ebay. Or just make do with the card you already had in your computer. If you are determined to have a better graphics card. A motherboard upgrade with better graphic card may be the best answer or buy a better spec pc second hand if you don't have much money. You'll probably waiste a lot of time trying to get the new card to work and it probably never will.

Hi sandesh8, did you know you can increase the memory size of the onboard AGP card above the 64MB? Page 26 in you're manual. If you install another AGP card into the opened AGP slot, please go to this site & only use the recomended AGP cards in the Asrock list. Click on this link: http://www.asrock.com/mb/vga.asp?Model=P4i45GV%20R5.0&s=478&c=VGA
This is one of very few video cards found on the list with 256MB of video memory.

Hi!

First of all i want to sugest you to make sure that you have maximum of memory, you gona need it if you want to edit videos.

If you want to do video editing the most inportant component is the CPU, then comes the memory, after the memory come the HDD, and after that the GPU

Now the GPU, you have a pci-e 16x port on that MB, so i will give you 3 diffirent sugestions, from a not that expensive to a more expensive to the third that is expensive but not the most expensive GPU there is, all of the very goos for vidoe editing.

1) SAPPHIRE RADEON HD4670 512MB GDDR3 PCI-E VGA/DVI/HDMI

2) SAPPHIRE RADEON HD4870 512MB GDDR5 PCI-E DVI

3) ASUS RADEON HD4870 DARK KNIGHT COOLER 1GB PCI-E DVI

There u have 3 very good GPU:s, but as i told you the most important is the CPU and the memory!

Good luck
Nic

Pc keeps shutting down


A) Computer is dirty inside.

Air is used to cool the hardware components inside the computer. If 'Gunk' blocks off the air flow, the Processor and GPU (Graphics chipset), will overheat.

[The Processor and Graphics chipset are the two hardware components that give off the most heat.
'Gunk' is Dirt, dust, hair, lint, food crumbs, you name it ]

If a Processor overheats it will turn off. (BIOS turns it off)
This is a fail safe feature built-in. Keeps the Processor from burning up. (Literally)

Power unplugged from computer, and Anti-Static Precautions FOLLOWED, a can or two of compressed air for computers is used, and Q-tips.

B) Power Supply has a weak voltage power rail. More than likely caused by bad Radial Aluminum Electrolytic Capacitors.
Check the three main voltages coming out of the Power Supply, with a multimeter set to DC Voltage.
Or borrow a KNOWN to be good, compatible Power Supply, for a test unit.
If bad replace.

(3.3 Volts, 5 Volts, and 12 Volts. All are DC Voltage. In comparison two D cell flashlight batteries produce 3 Volts - DC,

http://en.wikipedia.org/wiki/Computer_power_supply

Scroll down)

This is not a suggestion to open the Power Supply, and attempt repair.

The capacitors inside hold a charge for weeks, months, sometimes over a year.

If your fingers touch the terminals on the bottom of a capacitor, the stored charge could be released to YOU!
If your fingers complete a circuit that one, or more capacitors are in, the stored charge could be released to YOU!

Shock is Bad to FATAL.

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Capacitors need to be PROPERLY discharged before working on the unit.

C) Electrolytic Capacitors on the motherboard.
To be more specific Radial Aluminum Electrolytic Capacitors.

These are used on the motherboard as Filters, and 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 to regulate voltage to the Processor.
The Processor MUST have a steady, 'clean', supply of voltage, AND it must be kept within the small tolerance range for the Processor.

There are capacitors in a row near the Processor. These are SOME of the capacitors used for regulating voltage for the Processor.
There are others not nearby, and located elsewhere on the motherboard, too.

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

Be aware of this when looking for bad capacitors.

P5vd2 vm se with led no power


A) Could be a faulty Power On switch.

http://www.directron.com/atxswitch.html

Find the two pins on the motherboard, that the two wires from the Power On switch go to. Unplug those wires. Take a SMALL flat tipped screwdriver, and touch across those two pins.

Power Supply comes on? You have a bad Power On switch.
Is -> Not, the most conclusive test, but an easy one to perform off the bat.

There is a more conclusive test. If using this method the Power Supply does not come on, you have a bad Power Supply. If the Power Supply does come on, you have a bad Power On switch,

http://www.fixya.com/support/t13903733-bypass_soft_power_switch_friont_computer

[The Soft Power On circuit uses 5 Volts DC. In comparison two D cell flashlight batteries store 3 Volts DC. Just in case you are worried about shock ]

NOTE*
A Power Supply with a weak voltage power rail, will Not have enough power to turn the Processor on;

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

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

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

You either have a bad Power On switch, or a Power Supply that doesn't have enough power to blo-w it's nose.

You can test the three main voltages.
A) 3.3 Volts
B) 5 Volts
C) 12 Volts

Just use an economical multimeter set to DC Voltage.
You can purchase an economical multimeter for around $5 to $12.
Available in a multitude of stores. An auto parts store is but one example.

Need guidance post the multimeter's manufacturer name, and model number.

Green LED on board is on but computer will not start


1) Check to see if the problem is the Power On switch, or the Power Supply, first.

Use a multimeter on the two wires coming from the Power On switch.
Perform a continuity test of the switch.

How?
An economical multimeter can be purchased, for as little as $8 to $12. Available in a multitude of stores. An auto parts store is but one example.

Make notes, and a drawing as to where those two wires go, on the Front panel header, on the motherboard. Then disconnect the two wires, and hold them in your hand.

Set the Function knob of the multimeter to OHM's. (1K, or 10K)
Touch the Positive (Red) probe lead of the multimeter to one wire.
Touch the Negative (Black) probe lead of the multimeter, to the other wire.
Press the Power On switch. (Button)

You should see a brief reading on the multimeter scale. (Or readout if the multimeter is digital)
It is brief because the Power On switch is a Momentary Contact Switch.

No reading? Bad ATX power on switch,

http://www.directron.com/atxswitch.html

Good reading? The Power Supply may be bad.
Test the three main voltages coming from the Power Supply.

[NOTE*
The Switched-Mode Power Supply, (SMPS), in your computer, is a power converter. It converts AC electricity from your home, or business, into three LOW DC voltages.

The shock hazard is IN the Power Supply's case. Not from the low DC voltages it produces ]

A) 3.3 Volt power rail
B) 5 Volt power rail
C) 12 Volt power rail

Test at the 20-pin ATX main power cable's connector,

http://usa.asus.com/Motherboards/AMD_Socket_754/K8VX_SE/

Photo, shows the white, long 20-pin ATX main power cable connector, on the motherboard. No power cable plugged in.
Two rows of 10 socket holes.
(Above the blue Heatsink that sits on the Northbridge chip )

This is a 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

Power cable plugged in as shown in the right photo.
I suggest using a straightened out paper clip, and sticking it down in the socket for the power wire.
This is for the Positive (Red) probe lead of the multimeter, to touch to.

First voltage power wire check:
The multimeter function knob is set to DC Voltage. If just a symbol, the symbol is a dotted line, over a solid line.
IF there is more than one DC Voltage scale, for the Function knob to be set to, set it to the 0 - 50 Volt scale.

The straightened out paperclip, will go down into the BACK of the 20-pin ATX main power cable's connector, RIGHT NEXT to the Orange wire.
Has to go down far enough, to go past the Orange insulation of the wire, and TOUCH the metal terminal down in the bottom.

[Looking at the middle photo, you can see the tips of the metal terminals I am referring to.
Uninstalled, and end not crimped over the wire's insulation, this is what they look like,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

Left side shown, crimps over the insulation of the wire.
The far right side is what you are seeing the tip of, in the middle photo of the Playtool link ]

You can use ANY of the Orange wires you see. ALL are 3.3 Volt wires.
The Negative (Black) probe lead of the Multimeter, touches ANY Black wire.
ALL Black wires are Ground wires.
(Straightened out paperclip, also goes down in the Black wire's socket hole )

Put the straightened out paperclips in the appropriate socket holes, then plug the Power Supply into power. Press the Power On button, and start the Power Supply.

On the DC scale of the multimeter you should be reading VERY close to 3.3 Volts.

Good?
Go to ANY Red wire. ALL Red wires are 5 Volts (DC)
Positive (Red) probe lead of multimeter to straightened out paper clip, down into a socket hole, with ANY red wire.

Negative (Black) probe lead of multimeter to straightened out paperclip, in ANY socket hole with a Black wire.
Reading should be VERY close to 5 Volts. (DC)

Good?
Go to ANY Yellow wire. ALL Yellow wires are 12 Volts. (DC)
Reading should be VERY close to 12 Volts. (11.5 to 12 Volts)

ANY low reading means a bad Power Supply.

Primer:
1) If ALL of the LED lights 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 Processor can use 51 to 125 watts of power.

From your brief diagnoses it looks to be a bad Power Supply.
barely enough to light the green LED light on the motherboard.
Not enough power to even spin fans, much less turn the Processor on.

Power Supply checks out?
Perform a visual check of the Electrolytic Capacitors on the motherboard. Look CLOSE, and you may need a light, and magnifying glass.

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

Capacitors on the motherboard are used as Filters, and Voltage Regulators.
The one's used as voltage regulators, are in the motherboard voltage regulator circuit.
Some of the one's used in the motherboard voltage regulator circuit, regulate voltage for the Processor.

A Processor MUST have a steady, 'clean', supply of Voltage, and it MUST be kept within a very 'tight' tolerance range. Cannot be too much, or too little, or BIOS will not turn the Processor on.
(Or if on, will not keep it on)

That's an old motherboard. Could be bad capacitors, but I'm more willing to bet on a bad Power Supply.

OS INISTALLING ERROR


You might need to go into safe mode and install the motherboards' drivers before it can load properly.

Start your computer and hit F8 repeatedly until the boot screen comes up. Then select "Safe Mode". When it finishes loading up to windows safe mode then install your drivers from the drivers CD or go into device manager to install.

If you don't have a drivers CD go here and get all the drivers you need for your board:
http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?CategoryID=1&DetailID=505&DetailName=Feature&MenuID=24&LanID=0

From this site you'll see you need drivers for IDE, LAN, Sound, VGA (Video), Modem, Raid, and USB.

If you have a dedicated video card then you'll need to get the drivers for that too. Also don't forget to disable on-board VGA in Bios if you have a dedicated card and it doesn't do it automatically.

Good Luck!

Sync master monitor gives message smart image on and smart image off


This actually shows that there is a problem with the VGA port on the computers motherboard. If the monitor shows the smart image on and off, it means its okay but it is not receiving the signal from the computers VGA port. This could be a result of broken or bent pins on the VGA cable from the monitor, or there is a problem on the VGA port on the computer's motherboard. Usually in cases like these, we have to be careful and be exact as far as problem identification is concerned. So i would suggest the following steps for you to follow
1. Check for broken or bent pins on the VGA cable (the cable from the monitor to the computer), if all is well
2. Try a different cable, just to confirm (probably a new one)
3. Try to connect the monitor to another computer and see if it responds
4. Try to connect the computer to a working monitor.

These 4 steps will help you to identify which part is the problem. And since this looks like a hardware problem you might have to replace the faulty part with a new one

Browsing Facebook suddenly monitor crash.push reset button pc running but monitor sleep mode


Hi,
It's highly unlikely Facebook has anything to do with your problem. It's most likely a power supply problem or something blown on your motherboard. Connect a working power supply to your PC and try to start it again. If this doesn't solve your problem it's pretty safe to say your motherboard will need replacing.
Best wishes,

Intel d865gbf motherboard giving three peeps without ram but with ram no display


What display are you getting with Ram Memory installed? The BIOS Setup Utility?

Start with cleaning the Ram Memory module's, gold plated contact pins, with a pencil eraser. Reinstall, try again.

{ Power UNPLUGGED, Anti-Static Precautions followed. Don't follow Anti-Static Precautions, and you may as well remove the motherboard, and fly it at the cat }

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

If using an eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band of the pencil touch the contact pins.

The bottom of the ram memory module is where the contact pins are.
Start at the top of EACH contact pin, and stroke down.
Clean EACH contact pin. (There are 184 contact pins. 92 on each side. Doesn't take long to clean)

After cleaning with the eraser, it may seem as though you have done nothing at all. You have.
It doesn't take much 'corrosion', on a contact pin for a bad contact surface.

When satisfied the contact pins are clean, use air to remove the eraser dust, then reinstall the ram memory module/s.

However, when diagnosing a problem with a desktop computer, there are two components to check right off the bat.

1) Power Supply
2) Motherboard

Almost 80 percent of desktop computer failure, can be attributed to a bad Power Supply. Weak Voltage power rail.
(Next in line is the computer is dirty inside)

LED lights may light, and fans may spin, however there isn't enough power to turn the Processor on.

A) IF all of the LED lights were on at once, they would use less than 1 Watt of power.

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

C) A typical Processor can use from 51 to 125 Watts of power.
Depends on what Processor it is.

Intel Pentium 4 processor that uses a Socket 478 processor socket, and has a Front Side Bus of either 400MegaHertz, or 533MHz?

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors

Look under TDP in the charts.
(Thermal Design Point, or also stated as Thermal Design Power. Essentially the maximum power stated in Wattage, that the Processor may use)

Power Supply;
There are three main voltages produced by the SMPS in your computer.
(Your Power Supply is a Switched-Mode Power Supply,

http://en.wikipedia.org/wiki/Switched-mode_power_supply )

A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail

Power Rail:
Each voltage listed above starts in it's own central point, in the Power Supply. All of the wires carrying the voltages come from this point.

For example; Orange wires are 3.3 Volts. All Orange wires, end in one central 3.3 Volt point, in the Power Supply. This is the 3.3 Volt power rail.

Red wires are 5 Volts. They end at one central 5 Volt point in the Power Supply. The 5 Volt power rail.
Same for the Yellow 12 Volt wires.

To test the 5 Volt power rail for example, you choose any Red wire you see. (ALL Black wires are Ground wires)

Use an economical multimeter set to DC Voltage. (Symbol is dotted line over a solid line)
An economical multimeter can be purchased for around $5 to $12.
Available in a multitude of stores. An auto parts store is but one example.
{Need guidance in how to use post in a Comment}

OR, use a KNOWN to be good, Compatible power supply, for a test unit.
(Compatible being has the minimum amount of Wattage, at least, and the correct amount of power cables, and correct power cables)

Motherboard:
The weakest link of a motherboard is the Electrolytic Capacitors.
(Which the Intel D845GBF motherboard uses, and not solid Polymer Capacitors)

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

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 a very tight tolerance range.

See if you have bad 'caps',

Hello my laptop will not tun on when i slide thepower switch. HELP ME PLASE. PLEASE Thank you VERY MUCH


Check for voltage at the tip of the power connector.
If there's power there, try removing the battery and powering it up.
If that doesn't work, you can try a new power supply, but get a written guarantee that if the unit doesn't work, that you can return it.
If a new power supply doesn't fix the issue, even with a new power supply, then chances are unless you are an electronics technician/technologist, you aren't going to be able to repair the unit yourself.
Most places will want to replace your motherboard - don't use these shops.
Find a place like www.SuperTech-IT.com that does component level repairs and can evaluate and repair the motherboard rather than replacing it.
