Multibridge fan speeds up and down constantly

[Margus Voll]

Full shutdown and power off solved it.

Now i tested it a bit more.

1. i power mac down
2. connect MB power
3. boot
4. instant system crash or MB fans speeding up and down meny times and then crash.

I had this with previous version also so no question of driver.

Could i assume my MB is just died ?

Hi again.

Now it is really wierd.

I left MB on as separate converter and connected USB to it to monitor its actions.

When i got back in the morning the unit was so to say shut down. No power light.
Mains detaching did not change it.

Only when i disconnected units power cable it came back on.

BM little help please.
