Post subject: MotherBoard Fails to boot.
|
|
|
I've got an Intel D945GNT motherboard and a Pentium D 2.8 Ghz
processor. I've also got two sticks of DDR2 memory at 533 MHZ. I am
not able to get any video or even any post beeps out of the
motherboard. I've even bought a motherboard diagnositc board to try and
read any post codes, however I don't get any. I do see the cpu fan
twitch when I turn on the power and the 3.3v light blinks, but that's
it. I don't have any drives attached to the motherboard. I've replaced
the motherboard, cpu and memory. I've even tried to boot without memory
just to see if I could get any type of post code.
I've tired it with the motherboard mounted in the case and out of the
case. I've even tried different cases.
Anybody got any ideas? |

The +5 V standby power indicator LED (CR3J1) should remain
lit steady. It should not blink. If it blinks or goes off,
it means +5VSB is overloaded on the PSU, or the PSU has
protected itself by switching off everything. Remove the
motherboard from the computer case and assemble a minimum
system on your tabletop (with a cardboard covered phone
book underneath the motherboard for support). Removing
the motherboard from the case, ensures that no standoffs
are touching the motherboard, where they are not supposed
to.
Using CPU+heatsink+fan, motherboard, PSU, computer case
speaker plugged to the PANEL header, computer case power
switch plugged to the PANEL header, while it all is
sitting on a piece of cardboard, you should be able to
get whatever error beep pattern an Intel board uses.
Your port 80 POST diagnostic card should display
codes other than 0x00 or 0xFF hex, if all is well.
If the POST card is showing some activity, or you
get some beep codes, you can switch off and add
more hardware to the system, until you get really bad
symptoms again. Add RAM, video card, keyboard+mouse,
and finally a boot drive, in that order, and observe
the symptoms after each test case.
HTH,

As the other responder said.
OTH, if you've tried 2 motherboards and with not luck then you have to
look at your PSU and connections. Sometimes there's no boot if memory,
video card or wiring isn't properly connected. I take schematics on the
m/b over the scematics in the manual if the 2 differ. Also, make sure the
proper voltage is switched on the psu.
Just do a bare minimum, video, 1 stick memory, power, power on connector
and motherboard speaker. I think it's rare a cpu is the cause of such
failures. >> Stay informed about: MotherBoard Fails to boot. |

I have perfomed futher tests. I cannot take out the video or sound
since it is on the motherboard. I have tested with just one memory
module with no difference. I have no drives hooked up and I have tried
each memory stick and even tried it with no memory. I have checked the
cpu and re-seated it. I still get no boot. I do get the led to light on
the motherboard that shows it has power, but that is it. I have also
taken the motherboard out of the case and put it on a cardboard to make
sure I was not shorting out in the case. Still no boot. No beep codes.
No post codes on my post diag board.
Any other ideas? >> Stay informed about: MotherBoard Fails to boot. |

Well that eliminates sound and video issues. You only have the power-on
button connected, no usb, etc?
All power cables are connected to the motherboard? 2x12 and 2x2
connectors?
Is there a cmos jumper on the motherboard maybe it's set to factory ship
vs. normal?
What about your psu? Can you try the motherboard with a different psu?
LEDs require very, very little voltage to light. You need fans spining or
something to make sure everything is working.
Hard to image something wrong with motherboard when you have an Intel cpu
and 2 Intel motherboards. Intel makes some tough boards and cpus. No
offense but I have to go with a problem in your assembly skill, your
psu or memory first.
Try again then trying talking to Intel Help link. IIRC, they're pretty
good or send an email through their website. The website will probably
send stock email reply but replying to that email might get you more help.
And Intel honors it's guarantee, unless someone has clearly mangled the
cpu or motherboard. >> Stay informed about: MotherBoard Fails to boot. |

Try a different power supply and make sure you have all the
power plugs connected, particularly the 4 pin square 12V plug. >> Stay informed about: MotherBoard Fails to boot. |

I've found the light on the motherboard you were talking about. It does
stay on. there is a different light on the POST diag board that blinks
on for a second. I've tried several different power supplies and none
make any difference. I've tried it with just one stick of ram and
swithed which ram stick that's in. I've got no drives plugged in and
the sound and video are on the motherboard. I've even cleard the CMOS
and tried to reboot then. I still get nothing.
Any other ideas? >> Stay informed about: MotherBoard Fails to boot. |

At this point, the odds are it is a bad motherboard.
You've tried several power supplies, and all you can
manage is a twitch. I'd try another motherboard.

Cant be that, he's already tried another motherboard.
Gotta be that it doesnt like that ram since he's swapped
everything else or the bios doesnt support that cpu, unlikely. >> Stay informed about: MotherBoard Fails to boot. |

I'm curious at this point, as to whether the power is staying on
during all these tests. If the power is staying on, then I like
your theory. If the power won't stay on, then something else
is wrong.

He's already swapped both.

Its gotta be some fundamental problem like that motherboard
doesnt like that ram, or less likely the bios doesnt support that cpu. >> Stay informed about: MotherBoard Fails to boot. |

Not necessarily. Someone else got precisely that effect with
the bios not likely the ram and shutting down quite quickly.
That was fixed either by using ram it liked or by and
updated bios which worked fine with the original ram.
Posted in one of these groups in the last month or so.
Cant find it in groups.google for some reason, sure to be a brain fart on my part. >> Stay informed about: MotherBoard Fails to boot. |

Within the context of the thread in which I stated something
similar, it was true. Remember two things about that:
1) The board did POST. It was instable AFTER having read,
decompressed the bios.
2) It had no checksum error. If the bios was not intact,
had been written to, that would have been flagged
immediately with an error message. If it was a user setting
instead of the firmware itself, it would have been cleared
from CMOS.
The posts have to be in context, otherwise we'd be randomly
speculating about all kinds of things that are so unlikely
that it would take years to troubleshoot anything.

In the real world the above is true. Only in daydream mode
is anything made possible by ignoring the other evidence. >> Stay informed about: MotherBoard Fails to boot. |
