Arggghhh! What to do now with unknown non-working part?

Okay I posted a message here several weeks ago about my computer that I am assembling. Something in it does not work. I cannot figure out WHAT it is, because I have no way of swap-testing certain parts (I can verify that the video card and hard drive are fine).

It's a Soyo Dragon+, Thunderbird 1800 XP w/ GlacialTech cooler, Crucial pc2100 256MB, Gainward GF3 Ti200. Power goes to the motherboard, because it starts to POST, however it gives a long beep and then powers off. I have no way of testing the motherboard, CPU, fan or memory in another system ... so what am I supposed to do now? Although the motherboard manual doesn't have a very comprehensive beep-code table, it seems that it is a memory and/or video card problem, OR that the CPU fan is not working.

The CPU fan, however, IS working -- I can watch it spin up. I am tempted to just RMA all the parts to the places I bought them, but that isn't a very good solution because there is really most likely only one that is bad, and that will take FOREVER.

Does anyone have any ideas as to how I should go about fixing this? I have a ~$900 computer just sitting here and I'M GETTING DESPERATE!! 🙁
 
what type of bios is it?
Award beep codes:

<< The only AwardBIOS beep code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps. Any other beeps are probably a RAM (Random Access Memory) problems. >>


Also try here to see other beep codes.

Make sure the fan is connected to the right header. If the bios has some sort of protection for cpu rpm monitoring and you connect the cpu fan to some other header, it might shut down as it thinks the cpu fan is not working.
 
This might be the over-obvious suggestion...

But, does the CPU fan have 3 wires? If not, the MB might be shutting down automatically since it is not reading any speed from the fan sensor (3rd) wire. If this is the problem, I know there is a way to turn the auto-shutoff off for other Soyo boards and probably the same here. However, I think it's in the bios and you probably can't get that far. So, the easiest thing woul be to replace the fan...

or attach a bogus fan to the cpu fan header (so that the bios detects a fan working properly and then put the cpu fan on one of the other headers.

Hope that helps...

 
Is the cpu fan connected to the cpu header on the board?

Like Udimet720 said,most amd board come with a cpu fan rpm sensor & when it doesnt detect any rpms it turns off the board to avoid frying the cpu.
 
Yes the fan is connected -- and it spins -- I tried connecting it to CPU1 and CPU2, neither changes anything. Yes, the CPU fan has three wires. Hopefully today I'll get the chance to go grab a new fan and see if that works.
 
Maybe try a different tack: remove the ram and see how it beeps. If it gives a different beep, that could confirm that it is not a RAM problem. The same could be for the other components. I dont know if that will work, but its worth a try.
 
if you haven't already, double-check that the video card is pushed alllll the way into the slot.

i didn't on my computer, but it LOOKED like it was inserted ok, so it took a long time to figure that out...
