CPU dead or voltage issue?

[yocky]

I'm attempting a new build with an Athlon 64 3000+ on an Epox 9npa+
Ultra board. The mobo has 3 Ledion indicators which supposedly show
whether there is a problem with the Chipset, DIMMs or the CPU.
On powering up with RAM (2x512 PC3200), CPU and graphics (Gainward 6600
PCI-e) the first two LEDs are on but the CPU one isn't. I get power to
three fans (CPU, Chipset and Graphics) and the POST LED is on but it
just shows FF. I get no further.

I assumed the CPU was dud but thought I'd check the PSU voltages. It's
an Antec 450W PSU and it supplies one 24 pin and one 4 pin ATX
connector on the motherboard.
All the voltages seem fine apart from at the Grey PWROK connection
which shows less than 1V (about 0.7V from memory). I'm led to believe
than this should be measuring 3-5V.

Could this be the root of my problem, or am I overcomplicating things
and it's just that the CPU or motherboard is dud.

I've tried reseating everything, clearing the CMOS, messing about with
the RAM configuration, tried w/o the graphics card, but always get the
same results.

One more thing that's confusing me is the reset button on the mobo. The power on button works but the reset button doesn't, but I'm green enough not to know if reset should power down and restart completely or if I haven't booted enough for a reset to occur. (I'm talking about the buttons on the mobo not the case.)

That may do it yes, try another power supply, also check the epox website and see if other have that problem, I suppose it does not goot up at all?
That reset situation could lead towards a faulty Mobo

It was the PSU.

I would have tried a different one earlier but I didn't think the old one I've got had a 20/24 pin ATX and a 4 pin one but it does, it fired everything up straight off.

It just goes to show (I think) what a lottery it is. I assumed that because the PSU seemed to be working generally that it was working completely. I was ready to send the CPU back and would have done if it wasn't for the CPU Ledion indicator on the Epox board combined with my voltage check.

Quite a learning curve with this stuff isn't it?!
