After spending a couple of days searching for a solution across the wilderness of the internet, I figured it was time to register at a place where smart people congregate to see if I could get help with my specific problem...yes I am trying to butter you all up with compliments. You're all handsome as well. 
My problem: A few days ago I did a bit of an upgrade of my Late 2008 15" Unibody MBP. I put a new Crucial M4 256GB SSD in my hard drive bay and put a new Scorpio Black 750GB HDD in the Optibay. I then did a clean install of Mountain Lion on the SSD.
Everything works fine except that I can't shut down the MBP or put it to sleep. Let me get a little more specific so that you know what I'm dealing with:
Sleep: Whether I close the lid or choose sleep from the Apple Menu, everything goes as normal. Screen turns itself off, drives spin down, sleep mode is entered - for about half a second. The SSD then starts up again, followed by the HDD...and then spins back down again...and back up again...the screen never switches on. I still have to press a key or click the trackpad as I normally would to bring it out of "sleep" mode (when the lid is down, opening it doesn't bring it out) but the drives just keep cycling on and off.
Shutdown: Apple menu, shutdown...everything goes as planned...and then it restarts. Every single time. It stays shutdown for about a second then starts up again all on its own. The only way I can keep it shutdown is if I do a forced shutdown by holding the power button.
So, those are my problems. As I said, I've spent some time searching for answers and have thus tried various things so to save time, here's what I've already attempted:
PRAM Reset
SMC Reset
Deleting Dock plists
Deleting Power Management and Autostart plists
Turned on or off various energy saver settings
Disconnected Magsafe and tried sleeping/shutting down with just battery
Created new account and booted in safe mode to see if problems persisted (they did)
Strangely enough, when I did the SMC reset, the computer restarted itself as soon as I reconnected the power supply.
The only thing I haven't tried yet is a fresh OS install but given that I did that in the first place I'm not sure that would help and I'd like to avoid it if at all possible, mostly because it's a pain. If it becomes the only option, I'll do it but it's a last resort for me.
I'm beginning to think that it might be an issue with the SSD. I know people had sleep problems in the past with SSD's but that tended to be when it was in the Optibay. Mine is in the HDD bay. Would swapping it to the Optibay help?
Everything is working fine except for this and since the system boots quickly from the SSD, if I had to forget about sleep and normal shutdown and force shutdown via the power button, I guess I could live with that. It can't be healthy to force shutdown all the time though, can it?
If anyone can help I'd very much appreciate it.
