Motherboard Not Boot

by pdcjlw1 / October 17, 2006 11:55 AM PDT

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.

Bent Pin.

I dont have any drives hooked to the motherboard yet. I am still trying to just get the first beeps out. I did check the pins though and they look fine. None are bent or anything.

i've got the same board. the 'twitching' happened to me when i accidentally attached a 6-pin lead to the 4-pin lead (item E on the mobo layout, page 12 of the manual).

Power check
by pdcjlw1 / October 18, 2006 11:27 AM PDT

I have tested my power supply to make sure the supply is good. On my motherboard the power connectors are both labeled 13. I have both connectors plugged in. The power connector cloest to the cpu has only 4 connectors. That power connectors are plugged in correctly.

test with a different power supply

when the cpu fan flickers then stops, the cpu is not getting the proper power. since you've replaced the cpu, mobo, and memory, the power supply appears to be the problem.

changed parts?

?I've replaced the motherboard, cpu and memory.? ?I've even tried different cases.? In your main post is this what was replaced?

Motherboard replaced with new one? So that means BIOS went with the MB.

CPU replaced with new one?

Memory replaced too?

Changed cases so the power supply changed too or did you move it?

If you changed all these items than maybe some item is not compatible with the other parts. Re-check all the part specs and cross check with the motherboard manual. Any questionable mismatch of spec to requirement called for by the motherboard manual is the most likely suspect of the fault.
The parts being supplied are defective to start with. Perhaps the manufacturer is unaware they are making motherboards with the wrong or defective BIOS (or some other main component). Contact the manufacturer as directly as you can and inquire with serial number, bar code numbers, model number plus revision number, (from the motherboard itself) and date plus where purchased.
If any item above was not changed, it is the most likely suspect of the fault. Example if the power supply was not replaced, then that might be the fault.
