MotherBoard Siren

Well, Folks, I've done it again. This time it has happened while isntalling a new Power Supply. Took out the old one, stuck in my new one. Plugged everything in (was extra careful this time, I was so sure nothing was going to go wrong this time). But when i plugged everything back in, and turned on my pc, a Siren noise started going out as soon as i pressed the power button. After about 5 seconds of that, the computer shuts off. I searched google for "motherboard siren", some forums came up with similar problems, but never any definite answers of whether or not the ideas worked. So I figured I'd come here since this forum has never let me down. BTW, I tested both the old and new power supplies with only the motherboard and HD plugged in. Same thing happens. And all fans are functioning fine.


So here are the specs of my PC:
New PSU - ANTEC TRUE550 ATX RTL
Old PSU - Forget the make and model, but it was a 450W
MotherBoard - GIGABYTE|GA-7VT600-RZ KT600
Processor - AMD|2600/333 ATHLON XP BARTON R
Video Card - VGA GIGABYTE|GV-N52128D FX5200 RET
Memory - DDRAM TRANSCEND|PC3200 512MB RTL

I've checked gigabytes site, their online manual doesn't work(gives me an error when I try to open) and its search function doesn't seem to work, So I can't seem to try and search for the problem. And the manual that came with the MB is a joke, like 20 pages long, and not one page of troubleshooting or help. So any help is much appreciated.

Was there any reson to change the PSU ?
Apart from wanting to ?

Had there been any anomalies in the start up recently ? [it may be un-related to the PSU]

Asking, because the old adage still stands: If it ain't broke; don't fix it......

[edit]
I'll assume that the PSU was purchased locally [no voltage / frequency issues ?]
because it is possible that you've managed to fry the Mo/Bo, and putting the original PSU back wouldn't really help by then..........

Luck to you.

And BE [MORE] CAREFUL.:)

If you have a F/W up and running, it is possible that it is stoppin the manual from D/Ling. Try it with F/W disabled.

RE-ENABLE IT AFTER. DON'T FORGET :D

Funny thing, at work I burned out two Gigabyte Mobo's (will look up the type monday)..
Never had such things happen with an other brand..

Might just be coincidence..

"motherboard siren"

what is it just screaming at you or is it Beeps..

The manual will tell you jack ****.. if you don't know what your looking for.. the one that come with most of these boards is similar to the prinetd copy..

If it is just screaming at you.. have you been over-clocking the machine?
if it is beeping.. what is the sequence of the beeps? or is it a continuous tone..
HAve you bothered to try reseting the BIOS?.. dunno how with out the Manual.. pull the battery for an hour or 2...then reinsert the battery.. and reapply power and switch on..
Have you checked the seating of the AGP video card
Have you tried reseting the BIOS

BTW the manual has 40 pages..

there are no problems with the PDF file from the Gigabyte site.. what is the error your getting.. I hope you not useing any reader prior to version 5.05 (my test is with v7) reseting the BIOS is on page 16 at the bottom right of the page.. basicly what I said earlier.. except their advice is 30 seconds to leave the bat disconnected..

Replaced the old one because it wasn't large enough. When I installed my second HD, I had to unplug my DVD rom to make it boot.

Their site seems to be working now, so maybe i'll send their tech support an email. But the error I was getting was a page full of chinese symbols and other mumbo jumbo.

The PSU was boight on newegg, and I checked the voltages before I plugged it in, everyseemed ok.

As for the noise. It is screaming, theres no beeps. It literally makes a siren noise, just imagine a slimmed down firetruck. I'll go ahead and try flashing the bios. Nothing in my machne has ever been overclocked. As for the AGP slot question, I never even touched it, so I doubt it moved on its own. But anyways...Ideas, anyone else have some? Or is this siren thing like uncharted territory?

Ive never heard of a siren on a m/b before, there is usually a sequence of beeps that tell you what is wrong with it.

Just an idea but it could be some kind of alarm to let you now that the case has been opened, maybe you have to reset a jumper to turn it off or something along them lines?

Just tried flashing the bios, didn't help. As for an alarm jumper...the only one I can find it to clear the CMOS


--Do any of you think maybe a heat sensor or something was shorted, and maybe the alarm thinks something is overheating?

The ONLY time I've ever heard of anything like this was an instance where during bootup one of the keys on the keyboard was stuck, resulting in a sound that could be construed as a "siren". Food for thought.

haha...i wish. But that wouldn't explain the shutting off of my computer after 5 or so seconds of that. So would you guys say I could safely assume that this is being caused by a motherboard malfunction? Whether is be from a short in the circuitry or whatever unknown effect is causing this.

I'd normally suggest swapping out the Mo/Bo to prove the PSU being good.
But here, there is a possibility that you could fry another Mo/Bo..................

And to prove the PSU requires it to be plugged in.

Could you put the original PSU with a different - new Mo/Bo, just so we can be fairly certain that the old PSU is OK? and then we can start to assume that the Mo/Bo is indeed fritzed :smokey bang:
It doesn't follow that the new PSU is U/S, but, apart from physically stripping it down, and testing it bit by bit, I'm afraid that I'm out of ideas..........

Old PSU works fine, just stuck it in my brother's computer.

and Have you tried Reseting the BIOS? (well Clear the CMOS)

your talking about flashing the BIOS.. have you tried this? when did you.. what Bin file are you useing.. and how can you now if the machine will only run for 5 seconds?

When did this "siren" noise start.. before or after the replacement of the PSU..

puzzeled about the drive setup... you have 2 physical HDDS and a DVD rom.. but the DVD rom is disconnected because the system won't boot wit it connected? so what have you got pluggen into IDE-0 and what is in IDE-1 (primary and Secondary ide channels) and are the devices assigned correctly..ie master/slave..

Have you tried, trying to start the machine with only the hdd, video card, different keyboard, different mouse, NO USB devices, NO FIREWIRE devices (or leads), no internal modem, no other cards, one stick of memory, and for the hell of it.. no front panel leads connected.. well except for the power switch wires :)

But first and formost.. have you cleared tyhe CMOS (reset the Bios)?

Seems I'm a bit confused on my terms here...what I did was took out the battery for about 5 minutes, and put it back in, tried to boot the system. And I also used the jumper option to clear the CMOS.

The siren started after I stuck the new PSU in, and hooked it all up, and tried to boot for the first time.

As for my phyiscal setup, 2 HDDs, a DVD-rom drive and a CDRW drive. With my old PSU, I only had enough juice to run one at a time. So I chose the CDRW since I burn more CDs than DVDs I watch. I have both HDDs in IDE-0. 80gig as Primary and my 120gig Storage one as slave. And on IDE-1, I had my CDRW as a primary(being the only drive using IDE-1). All devices are assigned in a working order, Since I was able to install my PSU without having to unhook any IDE cables for the HDDs and CDRW, so the same setup was working with the old PSU.

Tried the system with only Video Card, 1 stick of memory in each slot. As for my front panel, All I have hooked up normally is my Power button and my reset button(Pretty basic tower).

Ahhh..ok..

have you tried your old PSU on the system--ok with the optical drives removed- You have already tested it in another machine so we know it works..and it did before in the machine..

If it works ok once reconnected.. then the problem is with the new PSU (strange but about the most likely at this point) it either is faulty, or a non-compatable ATX type (but hasn't damaged the Mobo)
Now if the system still errors You would have to assume that a problem has occured in the MoBo-
Probable causes :-
Random Failure
The PSU is a different ATX format and has damaged the mother board
or the psu is faulty and has damaged the mobo
CPU mounting, heatsink or thermal sensor failure,
A short has developed between the Mobo and the case (just another coincidence)

I am sure we could come up with more possabilities

cheers

Tested old PSU, same Siren error. Heres some links incase anyone wants to double check for me

It sounds as if you already had a problem to me.

CD + DVD + 2 x HDD.............that should run OK on 350W, let alone 450W :(

I am afraid it sounds like a MoBo fault to me, paticularly as you now get the same fault with the old PSU. I would just re-check all the connections, and that the fans are running properly. The symptoms do seem like overheating, but, as Undies said, that could be a faulty sensor? It might be worth checking the CPU seating and replacing the thermal compound (use SILVER, not the white muck). If you are lucky, it might be a real heat problem, and that will fix it.

I have come across case opened warnings, but they are usually visual, and the machine has to boot into the BIOS first. It sounds as if your machine isn't even getting that far?

Good luck

EDIT: These are your BIOS audible signals

well, the siren is new for me, but the sympton - 5 sec shutdown - is not.

a) processor is not correctly plugged in:
b) the m/b has a cpu heat protection but it can detect cpu fan. Did you connect the fan in the appropriate place?
c) cpu is overheat. May the heat sink/fan has some installation problem.
d) you had connected an 1.5v agp board, right?
e) you are plugging the power cable up-side-down :)

Well, tried re-hooking everything up with both PCs. Tried re-installing the processor/heatsink. Figures, its about time to give up. Newegg approved my return request. I'm still curious as to how giga-byte will respond to my email asking about the siren. But anyways, thanks for the help and suggestions. Maybe I need to look into a quick video for advanced hardware installation/setup so I quit frying my parts.
