Dragon+ no beep on power up, powers down after a couple seconds. Was a working system for over a y

I need some help from you experts/enthusiasts.
I have a Dragon+ board with 1.4ghz proc. in my system. This has been
running very stable since shortly after the Dragon+ boards started
shipping.
Last night, I asked my wife to shut down the PC (running WinXP Pro).
She turned the machine off via the power swtich, without going through
Windows shutdown. Obviously, this isn't recommended, but I've had to
do it occasionally on a few hang-ups, so this should be no big deal.
I went to power up the system later last night, and it would not power
up at all, just like it was unplugged or something. I unplugged power
and plugged it back in. The machine powered up for a couple of
seconds, then shut down. There were no beeps. I tried powering back
up, and got nothing again. I then unplugged and plugged back in
again, and it did the same thing as before, which was power up for a
couple of seconds and then shutdown, no beeps.
I opened the case and went through this same procedure (unplug and
plug in). All the fans are spinning up (MB, case, CPU, etc), the
disks appears to be spinning up (there is a light on the underside of
the disks that light up. The green light next to the JP5 jumper
lights up. Everything appears to light up, but then the system shuts
down.
I unplugged the machine, changed the CMOS jumper (JP5) to pins 2-3 for
over 5 seconds, moved it back to pins 1-2, plugged the machine in, and
tried to power up again. I got the same results as the previous
attempts. That's what the manual tells you to do to clear the CMOS,
but maybe I'm not interpreting the manual right. Let me know if that
is not correct.

I pulled the sticks of ram out and tried the same procedure, but got
the same results. put one stick back in, same results. Put both
sticks back in, same results.

The system is not overclocked (never has been), and as I mentioned
before has been running great for a very long time.

Does anybody have suggestions?

I tried calling SOYO, but just get there message service. The support
number in the manual does not appear to be valid anymore.
Any help would be greatly appreciated. I really like this board, so
hope it is something simple to fix.

Thanks in advance,
Gary

 

You did that just right.

I had a board exhibit that behavior--fortunately it was still in
warranty. RMAd it, and it was replaced. A capacitor had gone, and
taken one of the support chips with it.

All I can offer is--try the diagnostic steps on www.soyousa.com under
'Support' and look at the mini knowledge base there. My guess is that
something died on your board, but it's a guess only.

I was going to say, it sounds like a fuse was blown. I think the CAP
thing might be it. Try another power unit (borrowed if you can, ) but it
really sounds like a fuse or capacitor.

Try booting up the PC and press and hold the INSERT & DELETE keys. If
you can get the PC to stay up longer than normal, before shut down,
release the keys and see if you can enter the BIOS. If so, disable
the FOC in PC Health menu. I had a similar problem with my KT-400.
My computer room is slightly chilly, so the FOC would not recognize
the CPU fan up to speed/heat fast enough. The FOC will kick in and
shut the PC back down.

 

Can you try the motherboard in a defferent case? There mybe something wrong
with the power supply. Try a different case see what happens.

Dave's advice is probably good. A K7V Dragon+ has about 22 medium sized
green Wendell capacitors on it. These are among the type described on
http://www.overclockers.com/tips00140/. Look closely and see if any have
bulging tops. If you find any, the board is toast unless you get it
recapped. Soyo should do it for cheap if out of warranty, because they
used the bad caps in the first place. An alternative option is to get
someone else to do the recapping (e.g. http://motherboardrepair.com/),
or even to do it yourself.

Had the exact same problem with my Dragon 333 just today. I took out
the Firewire PCI card - that was in the center PCI slot - and
everything has been working dandy since...

Or, maybe your motherboard is shorting out - with your case. Maybe a
bad power supply.

Good luck.
