pc shutting down (not msblaster)

Farls

My spec

120gig sata seagate barracuda
AMD 2500+ (barton) @ 2 Ghz
Abit NF7 S
Crucial 512Mb RAM pc3200
Big Case lots of fans, no side on it
Win XP Pro, Red Hat Linux

My problem...

Since i put the computer together last september, sometimes when i put a full load on the cpu the computer just powers itself off to like a standby state and then it starts making beeps like a "nee naw nee naw" ambulance type noise.

To get the computer on again i have to hold the power button in for 3 seconds then the beeping stops and i can power up again normally.

At first i thought this was a heat problem so i bought a bigger heat sink and fan and installed mbm5 to watch the system temp, i've noticed that this "shutting down" event takes place wheather i'm at 40 degrees or 60 degrees ie. its not heat dependant it seems to be more to do with the work the cpu is doing.

I've played about with nearly every setting in the bio's even down clocking the chip to 1.4Ghz. But the problem still occurs. Last night though this shutting down took place when i was booting up and now i can't even get the computer to boot. It happens when i'm using XP or Redhat.

I'm also in the middle of doing my final year project so i'd be more than greatful for any help or ideas as to what the problem might be or a cure?

I myself am starting to think either the mobo or the chip or maybe both are faulty

Cheers in advance

Clear the CMOS to cure the boot problem, then try flashing the BIOS to a newer version and see if that cures the main problem.

What kind of power supply have you got? It may not be able to provide enough power when the system is under heavy load.

Farls

I cleared the CMOS, must try updating the bios....see when i boot at the moment it gets past all the loading the screens and windows starts up but when its opening up all the programs at the start (when the cpu is under full load) it goes to the nee naw stage!

I'll update the Bio's when i go home for dinner.

I just got a new power supply the other week because i thought that might of been the problem but nope!

Cheers

ps. you can appreciate what a setback it is to have your project nearly finished and sitting on a hdd that you cant touch A. because the pc won't work and B. because everyone else in this god forsaken town is still using ata!

what Gcard have you got also what PSU are you running your system on?

it sounds like you've messed around abit to much with the bios and now you've made another problem that won't allow you to boot your system at all, try resetting your cmos with the jumper on the board.

if you have any old parts laying around try swapping them around like try a different hard drive or replace the video card, disable or take out cards.

did you flash your bios? you may have flashed it with the wrong bios.
bios flashing is risky. i think alot of manufactures will void the guarantee if a mobo is flashed
anyway i hope this helps, maybe someone has had the same problem too and might have the answer, let me know if you get it sorted
goodluck

I'm using a Saphire Radeon 9600 gfx card, i had the problem before i put it in though.

The power supply i'm using is Hiper Powersupply ATX 350watt. , got it from komplett the other week. I never flashed the bio's when i'm home for dinner i'll clear the CMOS and try it. Then i'll swap the gfx for a bog standard one and try it, then i'll think about flashing the bios.

Never flashed the bios before but can't be too hard.

Cheers again lads

Disconnect any unnecessary devices.

My moneys on a dodgy optical device if u have any.

I have the logitech optical keyboard and mouse, now that you mention that though there is an optical sound port on the motherboard. Can't see how any of this would create the problem, i had the problem when using a normal keyboard and mouse.

Basic Beep Codes for ABIT AWARD BIOS Motherboards

No beep at all - this means your motherboard is dead, either due to a defective or underpowered power supply, poorly seated CPU or RAM, or a dead-on-arrival board

One beep - board is working fine

One long beep then machine shuts down - faulty, improperly installed or missing CPU

1 short(Beep) System booting is normally

2 short(Beep) CMOS setting error

1 long - 1 short(Beep) DRAM ERROR

1 long - 2 short(Beep) Display card or monitor connected error

1 long - 3 short(Beep) Keyboard Error

1 long - 9 short(Beep) ROM Error

Long(Beep) continuous DRAM isn't inserted correctly

Short(Beep) continuous POWER supply has a problem

A two-tone siren, generally caused by overheating or out of specification voltages

Four beeps then machine shuts down. This is because this version of the BIOS will shut down your machine if no fan tachometer signal is detected on the fan header. Make sure you attach a fan to the FAN1 or FAN4 header or clear CMOS to reset to default (no checking).


(Copied this from another site) Looks like overheating or voltage..

Farls

It does look like voltage, i never changed the voltage around though? And if it is then why did it work before and then shut down?

time to look for whats suppose to be the correct voltages!

big help that

I've the same board, what are your temps like? You have the m/b monitoring s/w installed?

Farls

yip have mbm5 installed, normally the computer's operating at 47 degrees at the chip with a case temp of 30 or there abouts, you ever get the shut down problem and the nee naw sound?

Farls

Farls

Right found a few websites with a few different ideas about that board, so all this bundled with your ideas should hopefully (fingers crossed) get things going now.

Away home to give this a shot, i'll let ye know later what happened

Sounds like a power supply problem. Thay make of PSU's isn't the best. If you have a lot of components and a lot of case fans then it may be having trouble under full load.

Is that your idle temp? If so, it's a bit too high and you could be triggering the BIOS temp warning (nee-naw sound)

If you're sure your temps are ok, you could try raising the BIOS warning temp by 10c and see if that helps.




If it is a BIOS temp issue, then a BIOS flash should cure it. If it's a temp issue, then reseat the heatsink with good thermal paste.
