Recurring hanging problem on boot

[meghatronic]

Just rebuilt my system (Asus P5W deluxe) and removed some old IDEs and one sata to reduce heat and noise. My computer always seems to hang right after detecting memory on boot, i.e. whilst detecting devices. This hang can be anything from 10 seconds to 5 minutes, but then boots quickly after that. I always assumed it was the other sata drive, as it was on the Jmicron controller, but apparently not, as I've removed that drive and disabled the controller. The problem still occurs. It's more annoying than anything else, but more ideas?

I have HDD, DVDRW, DVDRW all on sata in that order. IIRC onboard IDE is set to "enhanced mode" rather than AHCI or RAID.

My major concern is, Vista (non-sp1) used to do this hang on resume from standby. And the Jmicron drive would 'disappear' until a reboot. Sometimes some USB would fail too, prompting reboot. I always put this down to Vista and the Jmicron controller.

Any ideas?

I can always steal a keyboard from work. I'll try that.

Also, no beep as I have no speaker! I'll try long boot later.

Boot sequence is cd/hdd0/floppy so that's fine.

All of the main board sata are filled, and there are no IDE. So I'll disable everything, in addition to disabling the jmicron controller.
