Motherboard alarm driving me nuts

Specs: WinXP, 1024 MB

Okay, I swapped out the fan b/c it was getting slightly loud. Forgetting I had a CPU thermostat, I pulled that out. I put it back in between the fan and CPU, but the motherboard (or thermometer panel) plays an annoying alarm sometimes when I'm playing a game. The thing is, the temperature is only 42C -- this doesn't seem to hot to me. Also, it doesn't seem that this temperature is triggering it, although I couldn't imagine what else it is.

I didn't see any settings in the motherboard that had anything to do with alarm. I unbplugged both thermo panels just in case, and I still get this noise. I cannot figure out WTF is wrong with it. It seems to go off regardless during boot, then stops just as Windows is done w/ the boot process. Then starts again if I play a game.

Please save this computer a fateful fall from the 39th floor.

Alarms are never a good thing, they are always trying to tell you something is wrong. And the longer they are left unattended the odds are the worst it is going to get. I don't know if this helps but try visiting
It gives advice on what the beebs mean and how to correct the issue. Hope this helps.

Okay, weird. If my CPU is at 43 C and I start a game, the alarm starts. As soon as I quit the game (and the CPU is still at 43 C) it stops. O_o

Thanks for the link, Dan.

This is more like a police siren. Up Down Up Down Up Down... continual. I seriously doubt it coincidentally broke when I swapped out the FAN. I'll try to reset it, but I I seriously doubt that's it.

If you have the Asus board do you have AsusProbe installed?
The temp settings can be set if you have this.
Also make sure you have the latest BIOS updates, I had the same problems with my A8V Deluxe until I updated the BIOS which had a fix for the problem.
Worth a try.

Actually, it's an ABit. The Asus is in another machine. I'll poke around their site and see if there's anything of interest.

I put together an Abit KV7 with an AMD 2900+ for my wife and we have siilar issues with her PC. There is a Abit Windows monitoring tool you can install to let you view current fan speeds and temp and set the alarm thresholds. I have the alarm there set to about 50C myself, maybe you are seeing a default at 42C.

We have had a major problem with the system just powering off completely with the High-Low alarm you mentioned. I enabled the temp alarm and it sounds about the same as this but it goes off before the system will power down giving me a heads up.

Now on this PC we get this power off about any time we open more than two applications. Sometimes this happens at night or when the computer is idle and no one is using it but a couple of programs are open (mail, browser)

Since you mentioned playing games with would really drive up the CPU utilization on a system I suspect this is why you get the alarm. This would also be expected during a system boot since lots of processing and disk activity is going on.

Anyway I wanted to share this with you, seems like a problem with Abit possibly. This gets on my nerves though. I have a $20 cpu fan on there and I was thinking of replacing it to see what happens or adding another case fan. I have an AMD 3200+ on my PC using a Shuttle board and I never have problems like this.

I got this Abit as a package deal as I usually dont spring for that high end stuff but I can not say I will ever go that route again since I never see problems like this with other boards.

Thanks for the info -- where might I find this application. I'm looking on Abit's site and don't see anything of use (other than BIOS updates)

Did you simply check to see if tha CPU temp alarm is set too low in tha bios? Also my bios shows a higher temperature reading than my case temp sensor so maybe yo motherboard is tha same.

Be careful updating your BIOS: flashing the BIOs chip with the wrong updater will damage it and possibly the motherboard. You have to be certain what model motherboard you have. The best way to identify is by the BIOS string that appears when you first boot. Hit pause and write it down. there are sites that id boards by bios string.
