ive just built a system with a sempron 3000, every thing works nice when it boots up normally, but some times wen u turn it on the speaker on the mobo starts screaming and when u look in the case the fan has stopped?
Any idears anyone??? :confused:
 
Something is in the way of one of the fan blades, just catching it perhaps? Otherwise i would expect dodgy wiring, try moving the wires supplying the power whilst its on and see if the fan slows down or stops.

Check in your motherboard bios that there's nothing about turning the fan off when something is at a certain temperature.

I recently built a system for someone with a 3400 sempron in it - and the same happened as is happening to the OP - it was the above solution that sorted it out.
