Help! P4C800 Deluxe Wont Post

[Jerry Slaughter]

Hello everyone, need some input. I have built several machines over the
years, this is the first one I have had this type of problem with.

Components:

ASUS P4C800 - Deluxe MB
Intel 2.6c 800mhz Processor
2 sticks PC 2700 512MB RAM in positions 1 and 3
ATI Radeon 8500
Sound Blaster 5.1 in PCI 2
Lite On DVD CDR on EIDE slot
3.5 Floppy
Maxtor 20GB ATA 100 drive


The green light on the MB comes on when the power supply is turned on. When
I press the power button on the case the fans on the heat sink and the case
turn on for about 2 seconds, the keyboard flashes and then it all shuts off.
No beeps, nothing. Is it a dead board or a bad processor?

Thanks!
Jerry S.

Jerry don't panic,

Same thing happened to me after lapping everything. If the green light comes
on your board is okay.

Check your case to mobo wires, double check all your cables, connections,
and cards set properly, and the 4 pin PSU cable plugged into your mobo.

Push those DDR sticks in hard because they're tough and should snap or click
in. Look for any fan connections or wires that could be causing a mini lose
to ground.

Also make sure your P4 snaps in the socket. Mine, I had to push hard the
first time in. I got mine running fine after I did just what I explained to
you. I did use different IDE cables to doubly be sure my drives were hooked
up properly.

You know, reseat your PCI's and AGP again, and check the mobo standoffs
again, check those screws, etc.....

Hi there,

You could try taking out everything but the basics and try only 1 stick of
memory and see what happens?

You get EXACTLY the same symptoms you described if you forget to put
the 4 pin, 12 V ATX (square) power plug to the motherboard.

There was a batch of boards with a "solder blob" problem underneath
the S478 socket (bottom side of board - requires pulling the motherboard
from the case). See this thread and in particular a post by "Mechabouncer"
for more details:

http://www.techsupportforums.com/showthread.php?s=&postid=41955

A picture of the solder blob, which is underneath the plastic bracket
on the bottom of the board is included in the thread. The lower right
"blob" in this picture, is just barely touching the 12V track to the
right of the blob. There can be shorting here and intermittent operation.

Sometimes motherboards shut down if they detect no CPU fan is connected
or some kind of overheat circuit is triggered. You might also check
that the heatsink/fan is secure and is sitting flat on the processor.

As the other posters mention, simplifying your setup (removing hardware
unnecessary for basic operation), and/or assembling the system on a
piece of cardboard for your first test, might get you a little further
along. If there are brass standoffs on the motherboard tray that don't
align with a hole in the motherboard, remove the excess standoffs, as
they can touch a track underneath the motherboard and short it.

You guys called...the 4 pin connector. Thats what happens when you dont get
a manual and try to read the install instructions late at night off the
website....lol. Thanks!!!

Even when I change the case, or just cleaning the case by taking out the
board;
remounting the board with all connectors, 4-pin or the ATX-power 2-pin
confirmed,
it wouldn't boot for few hours. I had to take out everything again and
re-insert
3 or 4 times before it would boot again.

Fun and frustration mix well.
