This problem is often caused by the fan motor itself - particularly if it's the Mitsumi ' spindle motor ' type. The commutator gets noisy so when the fan starts up, you get spikes which cause the sytem control micro to shut the unit down. One stated cure was to add a 0.1uF capacitor directly across the fan motor, but failing this working, a replacement fan is often needed.

Hope this helps

Geoff
