MacBook :: Won't Shutdown / Restart / Sleep Or Startup Properly

During start up I get the apple logo and everything boots although it takes forever, the apple logo goes away screen goes blue, and sometimes it loads to the login screen about 10 mins later, and sometimes it just sits there. - During restart, it shuts down makes all the appropriate sounds, screen goes dark, and all you hear is a residual humming from the inside under the keyboard, and then never restarts. (You have to force shutdown) - Same story as above with both shutdown, and sleep.

The only way to get it to load successfully is in safe mode, but even then it still wont do the above problem correctly, it just at least starts.

- Resetting the PRAM, Holding power button for 5 seconds until repeating flashes, I've tried reinstalling snow leopard 5 times, I've checked for updates, I've repaired disk permissions, I've repaired the disk, I've even tried stepping the OSX back down to 10.3(The original operating software for this MB)
