beep code and cpu fan connection

[PtBetsie]

Now that I know the cpu is functional, I would like to determine that the motherboard is indeed also working. It doesn't post, I get a dash, dot, dot, which I thought was a video card error. The video card I am using is from a working system so it should work now. I removed it and reinstalled but get the same beeps.

My second question is on the cpu fan connection. If I connect the cpu to the pins on the MBD, it starts to spin but quits. If I connect it directly to the power supply, the fan works perfectly. :confused: Does this indicate a MBD malfunction?

I can't get into the BIOS since it doesn't post so I don't know if there is a change needed for the card I'm using.

Is this related to another post of yours?

If not, could you please start over, with a description of what exactly the problem you are having is?

Apologies for the confusion: Not a problem, just a learning project. I had rescued a MBD from the recycle bin, FIC AZIIEA, and was wondering if it worked. I previously asked about a cpu purchased on EBAY which came with odd instructions to use no thermal compound. With that answer I proceeded to work on my "puzzle". The MBD worked sort of after I changed the jumper to 100mHz FSB but I kept getting a beep code, no post. It sounded to me like video but I had used a known AGP video card. Today I borrowed an old pci video card and it boots up just fine. Can just parts of a MBD be not working? (AGP slot)

The other question I had was why when I connect the cpu fan to the cpu fan pins on the MBD, it doesn't work but if I connect it directly to the PSU supply, it does. Again can a MBD have bad parts but still be working?

This is a learning project for me as I don't need a 800mHz pc. If I know it will continue to work, I'll pass it on.

Yes, parts of the board can fail and still have most of it running...

Now, there are also other possibilities.

It is likely that the BIOS setting is to use the PCI/onboard video first. Since you can now see, you enter the BIOS, find the video card settings and change it to AGP, save the change, power down and retry the AGP card.

You can try to find any fan settings...as sometimes they are controllable from BIOS. If so you can try turning off the fan controls and running the fan directly from the PSU, because sometimes without a properly working fan POST will not complete.

There is also the chance that the fan is wired backwards from what the motherboard connector expects. You can try flipping the connector around (this may not work if the connector is 'keyed'). This can especially happen if the fan is a two wire fan and the motherboard is expecting a three wire fan (two wire fans don't have speed sensors built in).

The cpu fan connector is keyed so I kept the connection to the PSU. As for the video, I don't find many selections in BIOS. There is AGP Aperture Size; Agp-4x Mode; and AGP Driving Control/AGP Driving Value which is greyed out and not changeable. The first one is set at 4M and the second was set to 4X so I didn't make any changes there. Is there something specific that I should be able to find in the BIOS?

There is another fan on the motherboard but I don't know what it is for. The drawing in the manual shows the location but doesn't identify it. I assume it is another type of chipset; correct or unlikely?

[mjc]

Probably chipset.

The video card setting probably isn't on the same page as the AGP settings...but it should be there.

Thanks much! :o Actually I found the AGP "problem" was operator error. There was a MBD cd that came with the pc but I wrongly assumed it was just a copy of the manual. When I ran it just to see, it loaded lots of drivers including the one that makes the AGP work! Now I need to find a much quieter cpu fan before passing the computer on. It is so loud and at a high pitched frequency, but it was what I had on hand that would work for an Duron cpu. I suspect the MBD was discarded as the power supply was intermittent. Switching PSU's and it boots quickly every time. Thanks much someone will thank you indirectly.
