    Remove the and chake the beep if on beep your motherboard is foulty

  • Anonymous Feb 16, 2008

    The motherboard runs well but the display screen stays blank; the beep sound does not come out which means it does not find all the components.

If your motherboard does not give beep and display; remove your processor and ram and try working processor and ram on your motherboard, should there be no beep and display, your motherboard is dead.

    obviously working motherboard, working processor and working ram gives a beep after the post and with a good vga card - monitor gives a display; at the end of post[power on self test], there is no beep aquestion arises but there should be beep but no beep means no post no check on the hardware, no working system.

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',

My computer keeps turning itself off when it gets to the desktop and when I start it, it beeps at me, sounds like a 2 tone beep x2 my motherboard is intel D865GBF/B865PERC


One bad lead will cause your computer to shut down or continue in a cycle
replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA the ones that attach from your motherboard to your hard drive
hope this helps
