From: pdcjlw1 on 17 Oct 2006 21:35 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?

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, Paul

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.

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?
