Ok, im building a pc using a Soyo SY-K7VEM+ motherboard. I get everything connected and when i power it on I get 4 long beeps then the system powers itself off. The Soyo site says that means my CPU fan is not plugged into the CPU Fan 1 power connector on the mother board. But it is. The proccessor fan even comes on when I hit the power button. Ive even disconnected everthing from the board except the CPU fan. Still beeps. Any ideas people? Thanks!

More info on the type of bios and manufacturer would help in determining the beep code
The only one that had reference to the four beeps, suggest that this could be a timer problem,which could mean a bad motherboard.
Try resetting the memory and the video card to see if will work,if not then you will need to check the motherboard.

The motherboard uses a VIA KLE133 VT8361+686B chipsets and uses a Award PCI BIOS with ACPI function. I hope this provides some more help. Thanks!

Simple Solution with out a good answer:
The beeping is an error code, as you know. If you are confident your installation is correct, then I recommend a zero tolerance for poor manufacturing quality controls. Insist on a replacement or return it so you can choose another, hopefully, more reliable, brand. It should work without errors upon 1st correct install - no variance is acceptable, to me. (Of course, some bs always happens anyway, but that is my written philosophy.)

Well I do agree that we should all get working stuff when we pay for it. haha But I guess my hopes are that ive made some small error or missed someting, before I drive back and return it. But thanks for your input.

There are several CPU fan with only two cables instead of three cables.

The three cables fan, is used for monitoring purposes. Whenever the third cable is missed (fan is w/o monitoring), motherboard doesn't get feedback from the fan.

I think you should use a better fan with 3 cables. Or if you are so certain, then turn fan-monitoring off.

This fan has one connector with 3 wires going to it. (3pin) It simply plugs into a connector labled CPUFAN1. Seems simple enough, i know. I wish i could turn monitoring off. But i dont even get that far. It beeps and shuts down before it gets to detecting any video.

According to the Award BIOS information page, there is only one beep error code.

And that is one long and 2 short beeps for a video problem.

They state that all other beep errors are memory related.

Make sure that you have the correct styleof memory for the board. SDRAM, PC100, PC133, DDR

Try starting out with only Bank 0/1 installed.
Make sure that the latches lock onto the memory. That indicates that the memory is fully seated in the sockets.

Also, make sure the processor is properly oriented and seated to the mother board.

Finally, double check ALL mother board jumpers. Especially those related to the CPU and Memory.

You might want to take a look at your video card. I have one AGP card that some mother boards refuse to detect. It does not have all of the connection fingers present on the edge connector.
If you have a working "doner" system available, try swaping out the video card, memory, and CPU to try and narrow down the culprit piece of hardware.

Hi,

According to the motherboard's manual, there is a BIOS setting FOC (fan-off-control) which can be disabled.

It is enabled by default.

The extract from the manual (page 72) reads...

Default If enable, this function protect
user?s CPUfrom overheating in
an event there?s a problem with
the CPU FAN. The user should
also plug the CPU FAN power
on the CPU FAN1 pin. If not,
system will auto shutdown.

The URL to the complete manual is...

Cheers & Merry Christmas,
Tim.
