Siren sound from PC speaker when power on?

[Boylard]

Hi, when switching on my computer I get a siren from the PC speaker. The motherboard is an Asus K7M with an athlon 650, it never did this before I disconnected the cables and moved it to a different place. The computer appears to be working fine in win98 and the siren switches off when win98 has booted. However, I have just tried to install win2k on a different partition and it has all sorts of hardware conflicts (everything in a PCI or AGP slot is using the same IRQ?!), there are no hardware conflicts in win98.

Hmmm. Have you tried unplugging the speaker? http://64.209.212.135/cgi-bin/forum2/wink.gif

but seriously, take a close look at all your cables (especially power button/leds etc) and make sure they are all in the right way round.

Don't worry about Win2k, all devices with the same IRQ is a 'feature'.

Try updating the BIOS for the mobo, or at the last resort disable ACPI and reinstall win2k as this will force it to use different IRQs for all your devices.

ok check to see if your case,cpu or chassis fan connections are loose.
If the rpm signal from them is missing or below a certain theshold it will sound an alarm to alert you before something gets to hot.
check the the settings in the bios they may be set to high for the fan you are using and for that matter are you using three wire fans. if not set to ignore in bios.
