Hardware montor alert!

I keep getting a +3.3v alert in windows XP, on winbond hardware monitor.
I have set all default settings on my abit BD7II motherboard, and when the alert comes up, the voltage seems to be well within the limits, yet is still highlighted red, and the monitor recommends shutting down the system.
I am ignoring it for now, but can anyone tell me how to solve this?

cant you just adjust the low limit in wonbond so the alert wont sound?

OH!
I didn't realise that the voltage reading was BELOW the lower limit.
The message was saying that the voltage was too high!
Thanx for that stein!

Well, you can raise the upper limit too
