My machine started freezing and loading very slowly.  I replaced the hard drive.  Then it started this brief freeze and coding as if rebooting would begin, but then it would freeze.  If I turned the laptop off then back on it would reboot and run for about an hour, then repeat the process.  Thought the new drive was a dud and replaced it with a different brand.  Instantly the process started again (didn't even get Snow Leopard updated enough for Lion this time).  Thinking my baby is having a mother board issue instead of hard drive.  Is this the correct thought or do I have a simplier, less deadly problem?

MacBook Pro, Mac OS X (10.7.3), randomly starts reboot then freeze
