tc3100 beeps

[AnthonyB]

I have a tc3100, Win2K server, 3x18Gb Raid 5, 1Gb Ram.
Last friday it just started beeping. Traced the beep to the tiny logic board speaker.
The system seems to startup fine but sometime after all the POST checks etc, when Win2K login screen appears the beeping starts.

It seems that the default web server in IIS needs to now be started manually where it started automatically before but apart from that it seems to be OK - everyone can access everything they need to.

A tech colleague uninstalled HP toptools sometime before the beeping but don't know if its connected.

HP support initially suspected the RAID but thats ok and they say it isn't hardware so must be software.

Any ideas where I would start on this one?
