Computer Troubles with a Capital "Troub"

I spent a good chunk of time this week trying to troubleshoot a problem with my laptop. Starting last week, a BSOD -- Blue Screen of Death -- began popping up with precise regularity. If it didn't boot in Safe Mode, it wouldn't boot at all. As a result I had to dig into the "guts" of software, the bios, and all those things that I've largely detached myself from.

Not since the "good ol' days" of DOS on our family's trusty XT and later our 486 (which sported a "Turbo" button), have I been forced to understand the operation of my computer any deeper than pressing the button to turn it on or possibly downloading a specific hardware driver. This was full-on poking around in stuff that I didn't fully understand but kinda, sorta thought that changing settings here, there and everywhere, might goad the computer to boot up properly. It was a voyage of discovery as I came across settings and options that I often thought I should tweak, but never had the gumption to sit down and just figure it all out. (Of course, if everything was working fine, why would I start tweaking things?) There were completely unexplored areas and diagnostic options that I had no clue were present.
