For a while, all was well. Booted as expected. Loaded software. All on the first try. Then I got cocky..

I opened her back up (after seeing some solid cable management pics) in order to flatter my cables accordingly. I do alright. Get everything plugged back in. Flip the PSU switch then hit the power button. Its clear at this point that power is supplied to the system for maybe a second or two. Then it powers down. It tries again on its own. Down again. And again and again until I finally switch off the PSU and unplug it. I re-check all the cables assuming I forgot one or didn't plug one in all the way or something was kinked. Something.

Nothing.

I suspect the PSU went faulty. I check the output on each of the 24 ATX pins and all is well. The fan runs on the PSU when I short it's power so I'm pretty sure its not the PSU.

Next I tried to power up the system a few more times. Now it doesn't power up even for a second. I took the thing apart to comb it for shorts in the mobo. Put it back together. No response when I try to power it.

So that's where I am at the moment. Halp!

With only your cpu, cpu cooler and memory installed can you boot to the bios? You should see an error message on the monitor saying no system disk detected or similar notice. Are there any codes showing on the debug display? Is the memory installed in the same color slots? Try starting with only one stick at a time in different slots (first red, first black, second red, second black). Then repeat with the other module. Have you used the reset button and the start button on the MB? Disconnect all connections to the case (power, rest, audio, all) and try to start with the MB button. You can even try a start with no memory in. You should get an error telling you that no mem. is installed. The same for the video card. It can be removed and...

Do you see any lights (L.E.D.) on the MB when everything is assembled and plugged in. Do you see any MB lights when you press the power switch on the case? Are you sure you have power at the wall plug, try a lamp if in doubt. This sure sounds like a PSU died. But I would check all my connections again making sure everything is inserted all the way into the sockets and in the right direction. You can also disconnect everything from the PSU except the 24 pin and 8 pin connections to the MB. With only these two cables connected what happens? If it stays on then start to connect things one at a time. BTW you can not test the PSU with any sort of home meter. A PSU can only be proofed as working when tested under loads. Most shops do not have the equipment needed to do this.

Thanks for your reply.

Yes. The start and reset buttons light up.

No additional lights come on, no.

Are you sure you have power at the wall plug, try a lamp if in doubt.
Click to expand...
Yes. Triple checked.

Quadruple checked.

I'm pretty sure I checked this and the start & reset buttons light up. I'll check again when I get home.

I was testing the pins to ensure the correct voltage was being pulled through each pin. It was.

Something changed when you did the housekeeping. Check behind the back panel to see nothing is pinched. Try starting it with the side panels off. Did you route anything under the MB? This is a hunt and find problem.

I'll go through these when I get home. Thanks again for your help.

Also, this post is to remind myself to check that the power and reset buttons are connected to the right pins.

Bad news (I think). I have nothing but the PSU, cpu, cooler, and screen hooked to the mobo. Zero screen response. When I power up, The start and reset buttons light up but nothing else happens. When I short the PSU on its own, the fan turns on. When it's hooked to the mobo, nothing. Makes me think the board went bad. God knows why.

Need the video card to see anything btw. Put it in it's slot and be sure to attach whatever 6 pin power it needs. Try to start it again. The last test is to remove the components from the case. Set the mb on an insulated surface (like blocks of wood used to support it), attach the mem., video card, cpu and cooler to the mb. Then only the 24 and the secondary 8 pin to the mb and lastly whatever 6pin the video needs. Attach the monitor and see if it boots to the bios screen. If still nothing then something probably killed the mb.
