On a similar note, I melted the floppy drive's power cable after I didn't connect them up properly. Took me ages of shoving and pulling with a knife to disconnect the power cable from the floppy drive.
All in all, I just lost a floppy power cable. That's all. The drive works and I averted a catastrophe.
It seems that things are pretty bad for you right now, but they're not. I'm sure that a lot of good things are still happening to you, just that you're overlooking them a little. "Always look on the bright side of life."
Like your computer. You said that you nearly blew it up? But, well, you didn't. That was lucky, wasn't it?
Take care.
