It was pretty clean inside when I opened it up. So I went ahead and disconnected/reconnected all the SATA cables as suggested, and I popped the RAM chips out and put them back in just for good measure.
Started it up, got the same error message, went into safe mode and ran check disk. All was OK. Got out of safe mode and restarted Windows and all was good for some reason. I did get an error when Firefox tried to update, related to pagenation(sp?). Couldn't get it to repeat. It now boots OK and goes on-line alright too. I ran check disk on both the hard drives that are in it as I think I've got the slave setup for use by Windows. They both report back as good.
The one thing I haven't been able to find is a memory check to check the RAM sticks out, but they seem to be functioning fine for now.
Thanks again for the help.
