Have just installed new Novatech mobo bundle (m/b, AthlonXP2400, 256MB RAM) and all works fine, but there is an intermittent high-pitched whine from my HDD. This went away for a while after using a new IDE cable but has now come back. I know it may be just coincidence that HDD is on its way out, but wondered if anyone had any other ideas. Have done disk scan tests, surface scan etc with no problems being reported. OS is W98SE.
