I suspect there are a couple of problems here:
1) It's a fan failing. As they get worn they get loose in their sleeve and are susceptible to massive resonance spaz at a certain speed. Back in the day of dumb fans it was more likely at startup/shutdown as the fan passed over this certain speed.
2) something else.
Edit: I read the thread yesterday and forgot you said the noise was during startup. It's a fan. I lived with one for months and it's one of the few situations where kicking your computer will actually help :biggrin:
