Well Crud!
I got my mobo from F/A Mechdood today, happy as a lark I put it together and I get nothing! WTF is going on. Seems like nothing works in this computer anymore! I'm seriously beginning to wonder if my power supply hasn't taken a crap on me. Anyway to test a powersupply with a multimeter? I don't want to spend the money on an Antec PS tester just to find out that I need to replace it anyway...especially if I can test it myself.

Go to www.formfactors.org and download the ATX Power Supply Design Guide revision 1.3 (PDF file). Go to page 29 and it shows the power supply pinouts. You can then easily check your voltages with a multimeter.

Unhook the psu totally from everything...put a case fan or hard drive or something on the supply to give it a slight load..short the green wire with a black one...(that simulates the motherboard telling the supply to kick after you push the start button) I use a twisted paper clip stuck down in the connector.

Alright, now here's the deal. I pulled the PS and hooked it up to the old bad board, and I get fans a flyin by jumping the start pins.
I get the same thing with the new mobo....Here's the kicker....
I don't get any kind of signal to the monitor unless I short the reset switch and I get the led on the monitor to light up, and an audible response from the monitor ( good known monitor ) like it is getting a signal, and then it shuts back off. And this is only with the GF4 AGP card. My old Trident PCI card doesn't even get me that far. Why would the reset switch give me a signal and then a complete loss? I don't even get a screen yet. All I'm running at this point is my mobo, cpu, vid card, and a stick of ram...
Damn this is irritating! It wasn't supposed to go like this!

So it does the same thing using both boards? Have you checked your voltages? Any luck yet? | |

Well, time limited me to what I did last night up til my last post and I had to work today. I'm going to do more checking and see what gives.
The plan is to run the new board with the processor I got with it ( slower ) and no RAM out of the system. If that gets me no where, I'm going to pull the PS outta the wifes system and see if that solves my problems....
Although I'm not in much of a troubleshooting mood today.

Double Crud
Well, I'm up and running.....sort of. It seems that I ended up with the dreaded multiple component failure problem. Both my Abit and my new 1700+ bit the dust on me. I'm up and running again, still at 1400mhz, but with a Tbird instead of my happy Tbred Bcore  which is sadly out of warranty At least I'm running again. So, anyone interested in a dead KR7a and dead 1700+ ? 
On the bright side, at least I'm running like a champ again. Too bad I didn't know that both the processor and board died or I could have had most likely a running Epox board and RMA'd the processor under the 30 day warranty... Oh well, can't win them all.

That's bad luck. Glad you got it going, at least you know what it was now. | |

Well, the good news is, I was going to buy a 2500+ Barton originally, and now I can! The nice thing is that the processor I got from F/A Mechdood runs the same speed as my dead one...just a Tbird core instead of Tbred. So, I'm not losing out on speed, just OCability.
