Okay, so here I am.  

Today I plugged to computer back in (after unplugging it Friday night), opened the back panels, checked the connections, made sure everything looked okay (to me), put everything back together....and turned it on.

And it came on.

It's still running slow, so it may fall apart again (so if I disappear for a bit, you'll know why), but as of right now, I'm back and everything's going okay...so far.

Let's see how long this lasts...
