Don't get me wrong.
I'm a strong proponent of experiments and taking apart stuff. I'm a total hacker, in the sense that I'll happily take apart anything I don't understand to see how it works. There's only one motto I follow there: Re-assembly is dis-assembly in reverse order --- so keep everything in order when taking it apart!
"Uh-oh!" is the one thing my family dreads to hear from me when I'm "repairing" their stuff.
I'm sure there's quite a few here on this forum who can relate to that.
I've fu**up more machines, PCs and laptops than I care to think about and let's not even begin about software and such .... it's almost my life story.
When experimenting (i.e going on thin ice), just be very careful where to look for the issue as 9/10 it's PEBCAK.
So just keep up trying out stuff, think twice and try again before commenting and when you do comment: Be very specific --- it'll save a lot of time and space.
