Did you check the systems firmware? Here's Apples TN on how to check and update: [http://support.apple.com/kb/HT1237|EFI & SMC firmware updates for Intel-based Macs]

What happens when you boot the system off of an external HD or thumb drive which you know works correctly on a different like system? Does it still mess up?
