Are you using Windows 8 drivers ?
Windows Server 2012 has the same base as Win8 but no WHQL certified driver for it at this point.
check your copy of Windows in Device Manager under storage controllers.

when you say boot up are you talking about in Windows or during after POST when RAID BIOS is looking for drives ?
if it doesn't show up during the above screen it would be a hardware issue.
Could be an option in BIOS or something failing on the hardware level.
Did you check the S.M.A.R.T status on your hard drives?
could be spin up delay on the hard drives or a drive failing on you.
check SATA data and power cables (maybe swap cables if you have spares).
could be a firmware issue on the Hard Drives
At this point I would disconnect your SSD and do a clean install on your HDD RAID array
to test if you have a hardware issue or software configuration problem. as long as you don't
have any data on the RAID array (or have backups).
