Just tonight my PC started bleeping away at me. Everything was fine and the machine is still perfectly functional but I've found I'm getting a fluctuation in one of the voltages ( I havn't a clue what this relates to ...the cpu I'd imagine) its the +3.3 one and its now hanging around 2.8-3V and the alarm goes off intermittently. I've disabled the monitoring alarm for the time being but anyone know if this is going to be a problem ?? Machine has been fine for 4 months and it wasn't doing anything taxing at the time it the alarm started. I've started a trace on the 3.3V setting to see what it does over time.
