I thought the drivers might have been it.
600W PS is fine for your system specs.
I can't explain why it fails on boot then works later.... maybe it's using shared resources... hmm....I'll think on it.
Is the bios up to date, is the drive firmware current?
There's many reasons that the HD freezes the bios, most of which we've all mentioned (faulty hardware, chipset and sata drivers, cabling etc).
In regards to others comments about hot-swapping SATA drives. It is possible and part of the industry specifications for SATA. http://www.serialata.org/technology/why_sata.asp. However, it is risky as you may bump other connections or cause power surges that your PS or mobo may not be designed for. GregRocker said "It will catch up with ya quickly", I think it "will catch up with you eventually" :)
Lastly, if bios and firmware check-out. Maybe it's time for a reformat or an external case (borrow a friends if you can)..... any other ideas anyone?
