925XE Neo Platinum No Display problem

Please can someone try and help me out!!
System details are as follows:-
925XE Neo Platinum motherboard
Pentium D 945 CPU
2 X PC2-4200 513mb DDR 443
Radeon X700 256mb Graphics Card
Thermaltake Soprano Case
500 W Jeantech PSU
Maxtor Diamond 300Gb Hard Drive
Sony DVD rewriter

OK, the problem is that when everything is connected and I turn the PC
on, there is no display via the monitor. All the fans work (CPU, case,
& graphics card). The light on the keyboard, and the wireless mouse
receiver light up (so therefore power must be going somewhere), but
there is no display on my monitor.
I did have a Geforce 7200FX card originally for the graphics, but
swapped round thinking that something wrong with that, but still no
joy.
I have removed EVERYTHING, and started again fitting the CPU, fan,
memory, hard drive, DVD drive, floppy disc and then the graphics card
in that order, but still no display on my monitor.
I use an older PC and whilst the PC is turned on unplug from the VGA
and get the 3 wide colour bands. But when I plug into the new system,
these bands suddenley dim. I can turn the PC on, but these 3 colours
still stay dim. If i turn the power off to the monitor and then on
again whilst the new PC is running, I get nothing.
None of the lights that are suppose to work in the tower ie the power
LED or the HDD LED light up, even if I switch the cables round.
Anybody ANY suggestions, as I am running out of patience trying to get
this sorted.
Many thanks in advance to everyone who reads this, and even more thanks
to all the people who replay with possible solutions!

My preferred starting point, would be to take a multimeter and probe
the backside of the main power connector. Connect ground on the multimeter
to an I/O screw on the backpanel (easy if the meter has optional alligator
clips). That will leave you with a free hand to probe the rail voltages.

Since the 2x2 ATX12V cable can be on a separate cable, you also want to
touch the 12V pins (yellow wires) on the ATX12V and verify the processor
is getting 12V power.

If you don't own a meter, then component swap is a possible test.
See if you can dig up a spare power supply.

If all the rail voltages are present, and reasonably close (within 5%),
then the next suspect would be the motherboard. But no Power LED tells
you that there could be a powering issue of some sort, and that is why
I'd want to check that all voltages are present, by using a multimeter.
You can get one at the hardware store for $30 or so, and with clearance
sales after Christmas, you may find a worthy multimeter.

You've hammered the Reset button on the case a few times ?

Looking in Google, I don't see entries for your board, so I take
it the board itself is not trouble prone.

Hi Paul,
Thanks for your advice.
I've now used a different PSU, as theone sold only has a peak of 500w
and therfore there was no quarantee that it may be sufficient to power
the PC. The one I have in question now is a Jeantech 700w Storm PSU
after spending another £35!. With this PSU there is a wattage meter on
the back, so when I turn the PC I can monitor the wattage, which when I
do turn the PC it only gives a reading of 25w.
The lights on the D bracket are reading just the number 3 LED which
according to MSI means "ASSIGN RESOURCES TO ALL ISA." Do you or anybody
else know, in plain English what this means?????
If anyone can help you can email me direct at

Using the "ASSIGN RESOURCES TO ALL ISA", I ended up here. This
guy had a problem with his video card. So the LEDs and the source
of the problem, don't have to be related :-(

This page shows the LED values. The LEDs are not error indicators as
such, but progress markers. (They are about as useful as a Port 80
POST card.)

ISA used to be a bus in the computer. Maybe something like a
serial port, is referred to as an ISA resource ? In any case,
I doubt the text string associated with the display value is
that meaningful by itself.

http://en.wikipedia.org/wiki/ISA_bus

The fact that the power consumption is only 25W is a bit
puzzling. Based on measurements I've made here with a couple
PCs, I find while in the BIOS, the processor runs at about
half power. If system clocks were cranked to their normal
levels, you'd think the power would be higher than that.
Maybe the resolution of the Jeantech meter isn't that good ?

I would try removing hardware from the computer, and watch
how the D-bracket and the system speaker respond. Obviously,
with missing memory or a missing video card, you should get
some indication they are missing. The very fact that the
D-bracket code value is advancing ("counting up"), tells you
that the processor is executing some BIOS code. The question
is, what motherboard resource, or plugin hardware, is causing
a problem ?
