Hey
I am building two 3d/CAD machines.
Intel Core 2 Duo 2.4 ghz
Intel D955XBK MOBO with Crossfire
Seagate 500gb SATA 14 mb
Maxtor 40 gb hd
550w dual fan power supply
Kingston KVR667D2N5 1 gb x8
Masscool CPU fan with copper pipes
Samsung Litescribe DVD_RW
nVidia GeForce 6600LE 512 mb

I have 1 stick of ram plugged in, the 20 pin power cord, the 2+2 powercord that goes with the 20 pin, and a seperate 2+2 cord that plugs in next to the processor. I also have the CPU and GPU in the MoBO. BUT...No post. The fans all work, the mobo is OUT OF THE CASE on an anti-static surface. Also, when i take out the ram or take off the GPU, i get no beeps. The board has a built in speaker on the board. But i get nothing. Even if i take out the memory. I got the boards from and it seems like there is No BIOS whatsoever. Almost like i either have to burn bios onto the board, or its a bad board. The thing is, this would be boards 3 and 4 of this specific intel type that hasent worked for me. Any ideas as to the location of the problem? Thanks in advance.

Two members report the same symptom: power and fans spin but no POST and no speaker codes ( and ). That pattern usually narrows the problem to one of a few things: the board never initialises the CPU (BIOS/compatibility or bent pins), the motherboard is dead, the POST speaker is not working, or the system isn’t getting the correct CPU power. The following pragmatic checklist isolates the fault quickly.

  • Verify you actually have audible POST capability: attach a known-good PC speaker to the front-panel speaker header or use the board’s debug LEDs. A “no-beep” result with a working speaker means the board is not reaching POST.
  • Check power plugs carefully: the main ATX plug and the CPU 4/8-pin (EPS) must be fully seated and from the same PSU. Try a different, known-good PSU if available.
  • Minimal boot: with the board on a non-conductive surface and CMOS cleared, boot with only CPU, one DIMM (in the primary slot), and video (if no integrated GPU). No drives, no extras.
  • Memory and CPU swap: try a known-good stick of RAM and, if possible, a different compatible CPU. If swapping parts into a working board fixes the parts, the original board is suspect.
  • Inspect the socket: on LGA sockets check the socket pins; on PGA check CPU pins. Bent pins prevent POST.
  • BIOS compatibility: if the board shipped with an older BIOS it may not recognise a newer CPU. If the board will not POST, flashing the BIOS usually requires a supported CPU or a vendor BIOS-service. Check for any BIOS-recovery jumper or “flashback” feature in the manual.

If multiple boards of the same model fail out of box, favour a motherboard/manufacturing or firmware issue and pursue RMA or vendor BIOS support. Since later reports Asus boards worked, that outcome strongly suggests the original Intel boards or their BIOS were the root cause.

i have the same exact problem except i am using a 940 Pentium d processor. when i hit power all i get is a fans running and i know the hard drives are spinning, but i don't get any display from the video card, its like it doesn't know its there, granted yes it is a very old video card, does that make a difference is fits onto the board? Did you find a fix, if so what was it?
Thanks in advance!

o yeah i was looking at supported possessors to check myself and i don't believe that your processor is supported.

I was told by imfamous that it was supported.. I questioned it myself, but unfortunatlly i trusted them. Even if the CPU wasent supported, i should get some sort of warning beeps... I thought that it could have been a board where you have to flash BIOS yourself..IE Builder board... I purchased two Asus 60 dollar boards and they work great. the PCs are up and running, looking real nice in their translucent cases
