Can't POST After Shutdown

So I've assembled a system using a Gigabyte EP45-DS3L. I overclocked the pants off of an E5200, and the system was stable after a combined total of 24 HOURS of Prime95 Torture Testing, and 6 Hours of OCCT. Everything's great right? Maybe not. After executing a standard shutdown (as in Start->Shutdown) in Vista, the board won't POST when it's booted. I've scoured the Internet and I'm fairly certain that this is some sort of voodoo power management thing in either Windows or the BIOS, but I can't nail down the exact problem. Any thoughts?

I'm starting to wonder if it has something to do with the Power Supply. I have an Antec 550W, but it's one of those eco-earth-friendly deals. Hmm...

Some relevant details:

CPU: E5200 (Stable at 333Mhz * 10.5x = 3.5Ghz, 1.4125v)
RAM: G. SKILL HK 2x2GB PC6400 (333Mhz * 2.0x, 1.9V)
GPU: GeForce 9600GT

BIOS Settings:

C1E/C2E: Disabled
TM2: Enabled
EIST: Disabled
ACPI Suspend Type: S1 (Thought it might be this, but nope.)
AC Back Function: Soft-Off

If you've bothered to read this far, thanks a bunch for your time.

Oh and by the way, the board resets to its failsafe settings when it can't POST (very helpful) so I can get back into Windows. Once I do, I can 'Restart' and return to my optimized settings. I can keep 'Restarting' over and over with no adverse effect. So I suppose its not a devastating problem...but it would get really irritating to keep doing this every time the system is turned off.

Sound like a mem issue, not as in bad mem but incorrect settings. First are you running a current bios. If you haven't done so set your mem voltage & timing to manufactures specs. If that don't help keep the settings and try lowering your mem MHz and test.
