Re: Help with a loud computer...
The sporadic part does sound like a drive, since drives only spin up to max revolutions when you read/write directly do them. Although, if the noise is full-on throughout use, that's odd, since a drive that is spinning at full speed for an entire session definately sounds bad, or very badly fragmented/full of errors.
Can you elaborate on the noise at all? does it sound like a grinding sound, or more of a whirring, or clicking?
