Current setup:
DFI lanparty nf4 ultra-d s939
AMD64 3000+
Antec Neo Power 480W
evga 7900gt
I am currently in the process of upgrading the cpu to a opteron 165.
I had another thread last week about my DFI Lanparty nf4 ultra-d not working. I eventually came to the conclusion that it was dead and went looking for a replacement. I found another ultra-d locally and just picked it up tonight, but the problem is still there.

Here is a list of everything that has happened tonight;
-Came home, installed replacement mobo with new CPU, comp still wont turn on.
-take out new cpu, put old one back in, comp wont turn on.
-unplug ATX case wires to mobo, mobo turns on with old cpu
-try new cpu again, comp still wont turn on.
-decide to try old "broken" mobo with old cpu, and it turns on.
-try old mobo with new cpu, wont turn on.
-try both mobos with no cpu, both turn on.
so then I go back and forth for a while trying each mobo with the old cpu and with no cpu, then both keep turning on fine. But, then all of the sudden, they stop working. They wont turn on with no cpu and they wont turn on with the old cpu.
I now have both on my desk each on top of an anti static bag, I also have my PSU out of the case on the desk. I cant get either one to power on and ive tried all sorts of combinations;
-with or without cpu
-no ram
-one stick of crucial 512mb ddr-400
-one stock OCZ platinum 1gb ddr-400
-with or without vid card
I jump started the PSU with a paper clip and it does turn on, but could it just have enough life left in it to turn on its fans, but not the whole computer? How can I test m PSU to see if it is outputting the correct voltage. Ive got a volt meter, which wires do I need to test? The mobo has four power connectors on it; the big 24-pin, small square 4-pin, rectangular 4-pin (think its called molex) and small floppy connector. Do I need to test all of these?
Also, can anyone give me some ideas as to what else could be wrong or what else I should look at?
I do not get what is going on here. Up until a few days ago when I took everything appart to upgrade the CPU, everything was working fine. Ive been building computers for along time and I know what Im doing (except for that stupid chipset fan
but that seems to have been fine anyways), I dont see how I could have damaged anything, let alone the PSU. And with these power problems with the motherboards; they turn on, then they dont, then they do, now they dont, I do not get it. Anyone have any idea what the hell is going on?
As for the motherboards not working with the new CPU; the seller did have good heat, I do not believe he woudl try and scam me, it is possible that it could have been damaged during shipping. Or it could be that my mobo BIOS does not support dual core CPUs and would need to be updated to the most recent version, not sure if this is true or not.
