Solve : Building Computer Power test Problems?

Answer»

I desided to build my own computer beacause it cost lest better computer right will I'm havinf problems performing my first POWER test and could use some suggestions on whats wrong.

Ok so here we go, all I have plugged in is the CPU, heatsink, memory, and power suppley. Everthing is brand new and good and when I go to perform power test nothing my power supply buzzes and does not TURN on or turn blue.

But heres the part I can't explain. When I take a paper clip right and PUT one end into the green wire on the power cord and one into the black and then into there corrosponding spots on the motherboard the fan starts up blue and spinning i get beeps and the heatsink turns blue everthing works fine. But when I go to plug the cord back in to the motherboard nothing, and the connections is FIRM I know.

All i can think is its a bad cable loose wire or something. If anyone has any ideas would be of great help Thanks alot!!!

What brand of PSU is this ? ?

Are all MBoard connections double-checked and secure ? ?

More info.

patio. 8-)The motherboard is a gigabyte K8N Ultra 9 with an AMd proccessor and the power supply is a Thermaltake pure power 500w.

I have double and tripled checked all connections and they are secureAs a temporary check i would swap out the PSU and try another one...if the symptoms persist then maybe a bench test outside of the case on a rubber mat with just the bare neccessities to boot from;
CPU
RAM
Vid card
Primary HDD.

patio. 8-)This is the second PSU I swited it under warrenty and I did the test on the mat that the motherboard come on on top of the box so nothings in the case. Its just weird. The onlt thing I can think is bad cable maybe???It's either another bad PSU or something is not connected properly...

Start from scratch.

It's not impossible to get 2 bad components in a row...unlikely yes but not impossible.

Which cable would this be? The one from the case to the motherboard? Everything else would be new with a new power supply.Its the main power cable from the power supply to the motherboard. And yes its new like you saidQuote

I'll start from scratch again and SEE what happensWell I started from scratch again adn had the same problem. I even switched the power supply out for the one in my current computer that I know works nothing.


I mean this is the second power supply and motherboard. I dont think its possible to get both of them bad twice? or is ithave you checked all your jumper settings on your motherboard cause i had the same problem when i built one last year and just turned out to be jumpers in wrong placeI don't like hearing that your power supply buzzes. Could you have a short on your MOBO? this could be caused by a dropped object (nut, paperclip, etc) or by having the MOBO mounting screws in too tightly. You could try loosening them and retightening them gently.Or missing standoffs on the MBoard...those are kinda important too...
