This thread is of interest to me too as from new (Dec 2006) mu ASUS P5N32-SLI based PC has behaved what appears to be similarly
Normal boot
1: Power on
2: Wheeeeeeeee (all three fans start)
3: Several seconds pass
4: "Beep" from mobo speaker
5: Wheeeeoooooooooh (all three fans drop in pitch and volume as boot sequence proceeds and the three SATA and one eSATA HDDs start up one by one)
Occasionally though boot never gets parts step 2.
As a case in point, last night I got home to find the PC still at the "wheeeeeeeeeeeeeee" stage from a failed boot that the missus initiated two days previously (without realising she could safely press and hold the power button or simply switch off the mains supply to force power down)
