I've got a bad feeling about this...

Well, I got my RAM chip & power supply hooked back up, and mind you, I labeled all the connections, both the innies and the outies, before I disconnected everything.
Well, I don't know what I did wrong, or the fact that I fiddled with a dying power supply may have done it in for good, but my system didn't "see" that I had two hard drives. Therefore, I couldn't back up all my (and Miss Em's) data to the Seagate external. Nor make sure I saved all my current emails & bookmarks. So I'm bringing the whole box & the new Seagate to the Computer place and have him save all my stuff.
I hate it when machines are't logical.
