Thanks Paul,

I acquired a couple of other PSUs for experiment. I made some progress in
hypotheses. Here is my latest experiment.

"From my last experiment, I tied removing 12V and using my installed PSU.
Same result as last. Fans spin, LEDs glow, no boot recycle, no beep codes.
12V = beep codes." No PCI VGA boot to BIOS screen. 500MB DDR2-533
installed.
WTF?

My friend Jerry interpreted manual different he says default PCI VGA is
first. I say different. Maybe I should move format jumper on PCI VGA
graphics card?


Do you have another processor to test with ?
(No, not another 9650, a processor that will
start if the F4 BIOS is present in the BIOS chip.)

Something that you could use to start the motherboard,
then flash it up to a later BIOS version ?

I don't really think an unending supply of ATX power
supplies is going to do it this time. Just a hunch on
my part. This smells like a "we don't know what CPU this
is, therefore the measured VCore is wrong". But at least
we know the board only supports one VRD spec, the latest
one for that socket (LGA775). But that also causes a problem,
in that a few of the cheaper processors to use as a donkey,
to flash up the board, they wouldn't work either. VCore
might get shut down if those older processors in the "N/A"
category were used.

And what's a "format jumper" ???

"Format Jumpers" "Int ENA" are just tweaks on PCI VGA adapter. Not urgent. A
slow CPU might be as good an option as a slow PSU. My Q9650 CPU is supported
and it does work.

I failed to mention the old PSUs. One was DOA. Both were 20 pin ATX and no
4pin 12V connector for MOBO nor 6pin power for PCIe GPU.

I think my best bet would be to try an old PSU with 24pin ATX and four pin
12V connector for MOBO. In my past work I used multimeter to test 5V on PCI
bus. It hit 5V then declined (and then recycled) , a consequence of default
Power Saving BIOS setting and an over reactive (fast) PSU.

My GA-EP45-DS3L is BIOS v1.0 The latest is V1.1 BIOS is near perfect but can
be upgraded to V1.1. My last build went though 4 BIOS revisions. The fact
that some PCI VGA graphics adapters appreciate in value means that my
problem is not unique.

My GA-EP45-DS3L is virgin. This suggests that inventory is a LIFO (Last In
First Out) stack. EP45-DS3L was superseded by EP45-DS3LR, a trivial upgrade.
Used GA-EP45-DS3L(R) are coming online at greater price. For others I would
recommend used, where the previous user had applied all tweaks. However a
dead BIOS battery may have erased all settings. I would recommend an old
build that works. The fact of dual memory channels makes DDR2-533 viable.
And the Q9650 CPU has 12MB SRAM cache. DRAM is slow.

GA-EP45- MOBOs of various flavors are still viable in the marketplace. And
they are not expensive. But DDR3 is a rip-off unless on sale. Follow the
price curve. 4GB Samsung DDR2 RAM DIMMs are now cheap because of the price
curve. It should not be expensive for me to upgrade to 16GB dual channel
DDR2-533 memory. I am currently trying one stick of 500MB DDR2-533 RAM to
boot. One selects 'Load optimum defaults' in BIOS. Then I would insert one
stick 4GB Samsung DDR2-533 to boot, 4.5GB memory. That would require 64-bit
addressing that Q9650 CPU supports, then two sticks 4GB Samsung DDR2-533
DRAM DIMMs. I am not sure if 500MB DDR2-533 DDR2 would slow memory access,
but +500MB is trivial so why even try?

The purpose of trying a 512MB stick of RAM in your machine,
is to ensure that no BIOS issue can possibly take exception
to the amount of RAM offered.

On a machine that new, there shouldn't be a problem really.
But at this point, I would try the single stick of 512MB
until the machine shows you a BIOS screen, and otherwise
behaves in a "responsible manner".

I just feel at this point, the locus of symptoms are better
explained by a BIOS issue, than some external issue. As sooner
or later, all these ATX supplies you've been testing,
at least one of them should have worked...

You can use your multimeter to verify this stuff too.
Even I would have trouble, identifying good test points
to use for verification. Only DFI (Diamond Flower motherboards),
provided actual scope testpoints soldered to the motherboard,
with voltage legends silk-screened next to it, to make
home verification of voltage levels easy. Other companies
could at least put plated holes in the mobo with a silk
screen next to them, to make test point checking easier.
That wouldn't cost them anything to do (just a few drill holes,
which costs buttons in the grand scheme of things).

On this particular motherboard, they used holes filled with
solder for the monitoring points. You touch your multimeter
red clip to those and measure. The black clip on your multimeter,
can go to a grounded screw on the I/O Plate area if you want.

http://i4memory.com/reviewimages/mot..._utx58_dmm.jpg

I don't like to use multimeter probes on a power
supply, and get the probe tips too close to one another.
That's why I clip the ground lead onto an I/O screw
when doing this sort of thing.

I have the MOBO manual PDF. It has a two page long diagnostic flow chart
that I will spend time on first.


After I go back to flowchart I find short between frame ground and all PCI
pins. This requires further study.

The DVD R/W drive is connected to frame. Disconnect SATA data cable, no PCI
short to frame ground. WFT? Have other SATA cable. Try that.

Good SATA data cable does not give PCI short to frame ground. Two bad SATA
data cables give PCI short to frame ground. Progress?

Paul, not all SATA data cables are the same. Why?

Even with good SATA data cable, PCI short to frame ground, may be
intermittent. I'm not happy with MOBO mounting screwset. Some are too long
and cannot tighten MOBO at mounting points.

More study, labor.

Using a diagram of the PCI pinout (or the PCI Express pinout),
you will find some pins are ground. The motherboard logic ground is
joined to chassis ground (via the nine mounting holes on a full
sized ATX motherboard). The I/O connectors, the I/O plate has springy
metal fingers to joint the I/O connectors framework to chassis ground.

No attempt is made to isolate the whole system from chassis.

The safety ground on the three prong plug, should be joined to the
chassis ground.

You are allowed to test the system with no SATA cables in place.

You can bring up a machine and enter the BIOS, while no hard drives
or optical drives are connected. This would allow you to observe
system operation as SATA cables are added to a successfully running
(so far) system.

Thanks Paul,

I've even removed the beep speaker to find the short. Ohm meter says short
is low resistance. Step one in two-page diagnostic troubleshooting flow
chart must be wrong , or it is a bad, bad short.

Assuming Step One was wrong. I carried on down to Plug in Power supply. Turn
power on. No Beep, momentary power, system drops dead. Short must be real
and getting worse, or system is learning how to be more uncooperative.

The short to ground goes through the 4pin 12V connector.
