Re: Sytem Wont Start

Hi suisboy,

This sounds similar to a problem I had with a clients PC. The best way to debug this is to swap out one component at a time and see it it fixes your problem. However, if you can't do this then I'd suggest you try the following in this order.

  1. Remove all cards from the PCI bus leaving only the graphics card in place.
  2. Unplug all drive cables from the motherboard and power from the drives.
  3. Try to boot the motherboard. If successful try this, several time and if you don't have any problems you are okay to proceed.
  4. Enter the BIOS and load load the Default settings.
  5. Enter the BIOS and make it run the system check to fully test the memory.
  6. One by one re-attach your drives, if the system is stable continue to add you PCI cards until you hit the problem again. This will be the incompatible or faulty card.
This procedure should allow you to find the component that's causing your bus timing fault.

I hope this will help you diagnose your hardware.

Intel dual core processor is compatible for pi845z motherboard?


The Intel 845GV motherboard chipset will not support dual core processors,

The Intel Celeron D is NOT a dual core processor,

"The Intel Celeron D processor works with the Intel 845 and 865 chipset families.

The D suffix actually has no official designation, and does not indicate that these models are dual-core.

It is used simply to distinguish this line of Celeron from the previous, lower performing Northwood and Willamette series, and also from the mobile series, the Celeron M........"

Cpu suport

Going with problem heading stating ->

IBM 73P0595 motherboard > CPU Support > and previous problem statement ->
"I have updated my processor from INTEL Pentium d 820,2800mzh 1500mzh to INTEL Pentium d 945,3400mzh....."

Let's take a look at the IBM 73P0595 motherboard specifications, first;

A) Socket 478 processor socket

B) Intel 865G motherboard chipset,

The Intel 865G motherboard chipset DOES NOT support dual core processors.
Does NOT support an Intel Pentium D; 820 OR 945

Those two processors also use the LGA 775 processor socket.
(Socket T, )

What did you base your CPU support on?
Was it the fact that the Intel 865G motherboard chipset, will support Intel Celeron D?

The Intel Celeron D is NOT a dual core processor,

"The Intel Celeron D processor works with the Intel 845 and 865 chipset families.

The D suffix actually has no official designation, and does not indicate that these models are dual-core.

It is used simply to distinguish this line of Celeron from the previous, lower performing Northwood and Willamette series, and also from the mobile series, the Celeron M......"

Not the IBM 73P0595 motherboard we're talking about?


Let's just base it on the statement that you tried to upgrade, from an Intel Pentium D820 to an Intel Pentium D945,

What motherboard are you using?
Motherboard in a HP Compaq DC7600 Desktop PC?

Scroll down to the bold subheading -> Processor and Speed

Intel Pentium D820 at 2800MegaHertz (2.8GigaHertz),
with 800MegaHertz Front Side Bus, is supported.
(800MHz FSB)

Probably came with your computer, huh?

Intel Pentium D945 at 3400MHz (3.4GHz), with 800MHz FSB is supported also.

This can be seen by the specifications of the motherboard chipset, also. The Intel 945G motherboard chipset,

Scroll down to 945G in the left column. (Last one listed in chart)

Apparently you just needed the 786D family Processor Microcode Update, or did that not work out?

Awaiting reply,

(How did I come up with the HP Compaq DC7600, anyway?
Did you add it in a Comment, and it has been removed, or what?

!O_O! )

Click the "Start Menu.

Right-click on "My Computer."

Select "Properties." By default the Properties window will usually be set to the "General" tab, but if the window is set to a different tab you'll need to click on the "General" tab located near the top of the window.

Check the CPU rating as listed underneath the "Computer" heading.

Determining Real-Time CPU Speed

Go to CPU Speed Professional's website (see Resources) and download "CPU Speed Professional."

While other free CPU clocks exist, many are beta programs with glitches and unwanted bugs. CPU Speed Professional is well-known and reputable, receiving the "Vista 5 Star Software Award" according to its website.

Install the recently downloaded

" "

file by double-clicking on it and following on-screen prompts to complete the automated install procedure.

Open CPU Speed Professional.

Click "Test Your Speed" on the main program interface.

A real-time, active measurement of your CPU speed will appear numerically, and CPU Speed Professional will also display your CPU speed on a stylish meter for easy visual comprehension.

hope this helps

Support dualcore?

That is a socket 478 motherboard. I doubt that one even gets dual core processors in the 478 chipset. Also according to the ECS website, this is a Pentium 4/Celeron board. More info can be found here.

I like that. Kinda' rhymes. "Fan OK but no Display"

Problem is your Processor isn't turned on.

You have a bad Power Supply.
> Weak voltage power rail.

You probably have a 200 to 300 Watt power supply. (SMPS)

1) ALL of the LED lights together use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor can use 51 to 125 watts. Depends on what Processor it is.

The Intel D845GVSR motherboard uses a Socket 478 processor socket.
Supports Intel Celeron, Intel Pentium 4, and Intel Celeron D, that utilize a Socket 478 processor socket, and have a maximum FSB of 533MHz.

Utilizes the Intel 845GV motherboard chipset.
[ Intel 82845GV Northbridge chip, and Intel ICH4 Southbridge chip ]

89 Watts is the maximum wattage, that can be used by a Processor for the Intel D845GVSR motherboard.

Power Supply has enough power to light LED lights, and spins fans, but not enough to turn the Processor on.
No Processor operating, No computer.
No computer, No video signal to the monitor.
(No Signal)

Do you have access to a KNOWN to be good, compatible Power Supply, for a test unit?
