Today I built an amd64 3000+. Well I've never built a computer before but I'm not a total newbie. Anyways, Everything is plugged in, and I go to hit the power button on the case and nothing happens. When I plug in the power supply to the wall, I hear a quiet but high pitched squeel. And thats all that happens. No fans spin, the heatsink fan doesnt spin. Nothing. Is there something noticably wrong here?

Also I brought it over to a friends thats pretty new as well, and we plugged in his 350w power supply to my motherboard and after about 4-5 times of switching it on and off, the power supply blew up a big blue spark.

Here are my specs and hardware that I am using,

ASUS k8t800 mobo
amd 64 3000+
corsair select 512 mb ddr
Linkworld case with a 400w power supply


Is there by any chance that I didnt put in the processor right? Like I put too much thermal paste on it? I put a very thin layer though so I don't think thats it.

It cost 65$ to have a tech look at it, so Id like to try and fix it myself. Could it be a defected motherboard? Defected proccessor?

All I know is that nothing works or spins when I turn the system on. And when I plug in the power supply cable into the wall theres that quiet high pitched squeel for about 2 seconds and stops as if it just started up or something.

If you have not used the correct spacers and the correct locations for the spacers on the motherboard mounting, you may have shorted the motherboard to the case. That can cause the problems you mention (plus possible damage)

If the ps you had hooked up shot out a spark, I would suspect the mb, processor, ram, and anything else you had connected at the time of the shooting sparks. Here is my list of instructions for “Problem builds”

1) Remove EVERYTHING from the case
2) Set the motherboard on a non conductive surface. The motherboard box is perfect for this. .DO NOT PLACE THE MOTHERBOARD ON THE STATIC BAG! It can acually conduct electricity! We are going to try and assemble a running system outside of the case.
3) Install the CPU and heat sink.
4) Install the RAM (only install 1 stick for SDRAM or DDR ram, 2 for RDRAM)
5) Install the video card
6) Connect the monitor to the video card.
7) Connect the power supply to the motherboard.
8) Connect power to the power supply
9) Do NOT connect ANYTHING else. Make sure you have the power connector on the CPU fan connected.
10) Use a small screwdriver to momentarily short the power switch connector on the motherboard.

If all is well, it should power up and you should get a display. If not, then you most likely have a faulty component. Do this and and post your results, then we will get it all assembled in the case and get this thing running.
