I just finished installing a new motherboard: Gigabyte M61P-S3.
Everything is brand new, including the Sata-II hard drive. So there is
no operating system or anything. I plugged it in for the first time
tonight, hoping to start programming everything and I'm already
running into problems. Firstoff, the new 12-volt main cooling fan is
not working (I plugged it into the "cooler fan power connector" on the
motherboard). Secondly, my monitor won't kick out of sleep mode when I
turn the computer on. Any ideas why this could be happening?

Are both power plugs connected ? There would be a larger main
power connector, plus the 2x2 ATX12V connector that feeds
the processor.
I was afraid of this. My processor fan is working. So I figured it
might be the main power connector. I'm using an old workstation mini-
tower. Which is making access mighty difficult to connect that plug
(but not impossible). The real problem is the lack of support behind
the main power connector. I'm scared that if I force the plug too
hard, I'll crack the motherboard. I tried to get my other hand in
there to hold the outer edge of the board (the plug is located on the
edge of the motherboard) but there isn't enough room for both hands!
Are there any tricks (or tools) of the trade? Has anyone else run into
this problem? I wish the darn plug would just snap in place, but that
would be too easy. What can I do? There must be a better way of doing
this without the risk of breaking the board.

Hold on there, sparky.
What are you forcing ?
The insertion force shouldn't be that high. Make sure you are using
the correct connector. I just checked the 2x2 ATX12V connector on
my spare computer, and the 2x2 inserts with fingertip force. I
can seat the connector and have the little latch snap, by using
only one fingertip.
The Mini-Fit Jr connector family are keyed. The plastic on the male
and female connector parts, have shapes. The shapes prevent the
thing from being plugged in the wrong way. In theory, the connector
should only fit one way. You can use the latch on the connector,
and the mating gadget on the other one, to figure out the correct
orientation.
Before you do anything else, could you tell me:
1) Make and model of motherboard.
2) Make and model of power supply (check the label on the PSU)
I want to make sure I give you good advice. For example, there
are motherboards with 20 and 24 pin connectors. There are
power supplies with 20 or 20+4 main connectors, as well as
the completely separate ATX12V 2x2 connector.
It is a bad thing, if you remove the "+4" part of a 20+4
hinged connector, and insert that "+4" part into the
ATX12V 2x2 connector. So if you tell me more about the
equipment, I can review what you should be doing.
The Motherboard is a Gigabyte M61P-S3 which has been installed into an
old Dell Precision 420 workstation "mini-tower". http://i70.photobucket.com/albums/i9...g?t=1203489114
I haven't tampered with 20+4 plug in question: http://i70.photobucket.com/albums/i9...g?t=1203489157
I know, it's not a great photo. The label on the power supply says
"Lead Power" model: LEAD-600 (600w max). I think I probably should've
got some of those rubber feet to put behind the motherboard for
support. I'm not really forcing anything ("force" was probably the
wrong word). It's just that there's really no support in that
particular area behind the plug....I'm afraid to push too hard.
Hopefully you'll have a better idea than the one I'm thinking of
(disconnect everything and remove the board to install those rubber
supports behind it).

Older Dell machines have non standard ATX power supplies. The faded
colours of the cables in the photo would seem to suggest that the
original PSU has been retained. You would have been better off buying a
new case in the first place.

The "mini-tower" here lists 410W. You have a 600W supply, so I guess the
supply has been changed ? I would think, based on the motherboard description
in the Precision workstation 420 (dual Pentium III, 840, rambus), that
it would have been highly unlikely to have a 24 pin main power connector.
And an old computer like that, probably would not have had a 2x2 ATX12V
power connector either. (Introduced in P4 era.)
OK, there is a picture here of the old motherboard. I downloaded one of the pictures,
adjusted contrast and brightness in Photoshop, and I count a 2x12 connector
and a 2x8 connector. So if you really have the old power supply in there,
chances are, the connectors are not the right type. Back in the days of
things like the P3, a 20 pin main connector would have been the standard,
so it isn't likely, if they used a 24, that it has the same pinout as
today's 24 pinner.
If you want a spec for a 24 pin power supply, the kind you might use with
the M61P-S3, you'd look here. Compare the wire color listed on page 37
for the 24 pin connector, against the connector you are using. While
your photo matches the colors, for half of the connector, I cannot see
the other half.
These are previous generations of ATX standards, for reference if you need them.
The last one, the 1.1 version, is from the days when -5V was on the main connector.
Based on the picture, I see that your "20+4" connector is slightly askew.
The 4 pin part looks seated, but not the 20 pin part.
OK, since the board is 12" x 8.6", the holes on the right edge of the
motherboard would be missing. And you're right, the connector, since it
is right out near the edge, is unsupported and flapping in the breeze.
All you have to do, is place the right sized object underneath the edge of the
motherboard, to give it support. If you have some spare standoffs, put
them under there. I'd probably find a scrap of wood of the right
thickness, to stick underneath there. Then you should be able to
finish seating the 20 pin portion of the 20+4.
When you're finished, the "ATX_12V" connector shown in the manual, should
have a 2x2 connector, with two yellow wires and two black wires, plugged
into it. The main connector is 24 pins, and you can verify the wire colors
against the ATX 2.2 spec above (page 37).
Don't turn the power on, until you've verified everything is in order :-)

The color and position matches a new 24 pinner, so I don't think
he's blown it yet :-) Based on his motherboard manual, the visible
wires (pin 1 in lower right corner) are the right colors. I can see
the color of the wires on 1 thru 12, but can't see 13 to 24. So
he'll have to check those are correct as well. I suspect he has
a modern supply mounted in that old case (why, I don't know - like
how it got there doesn't make sense).

Does your new video card have an auxiliary power connector? Have you
connected it up to the PS harness? Monitors come out of sleep when they
sense video and I believe that many modern video cards won't even begin
to work unless they have the secondary power feed.
Also, if your video card has multiple outputs (DVI and analog for
example) it may be possible that the wrong one is coming up active and
is not feeding the monitor -- I got bitten by this one myself some years
back. I'd would have hope by now that the manufacturers would have all
gotten such trivialities sorted out but I wouldn't bet on it.
I do have a video card, but the monitor is not plugged into that yet
(it's plugged into the motherboard). I want to get my bios set up
first, then I'll worry about installing the drivers for my cards,
printer, etc. Paul, thanks for all the information. I'm going to cut a
piece of wood and hopefully there will be enough room to get it in
there. Martyn, I'm using a Lead Power ATX power supply (identical to
the one Paul posted a picture of). The case is the only part of the
old Dell that's being used. Everything else is brand new right down to
the CD-Rom. I don't know why, I just like the basic beige tower.
