@Wayne,
Unfortunately there's always going to be problems that arise with computing - it's the nature of software. Have you ever tried solving {bleep}y problems on WindowsXP? Quite often it's a real nightmare, and even if you're a competent computer user you can often be left scratching your head and digging for the XP Install disk (again).
If you're a regular computer user who doesn't have a team of IT staff on call to repair your computer all the time (i.e. you're a home computer user) then unfortunately you're always going to need to know a little bit about how the OS works. If you're a serious home computer user then really you need to be completely happy when under the bonnet - it's no use pretending that you don't need to know how things work when problems are arising and you've already got valuable data stored on the machine.
