ABOUT THIS BOOK
Let’s get the apology out of the way first: we’re sorry. Sorry because
from the mere act of picking up this book and flicking through it in
the bookstore, or scanning its first few pages on Amazon, we can
tell that you’ve been there.
You’ve suffered from one of those knotty computer problems that
make you want to shove your fist through the screen, just so you
never have to see that impenetrable error message ever again. We
feel your pain. How many sugars do you want in your tea?
We can’t promise to solve all of your computing ills – there’s not
enough ink and paper left in the world to cover every conceivable
computer fault. But we can promise that we’ve covered most of the
major problems that might befall a PC or laptop and have provided
no-nonsense advice on how to deal with them.
What’s more, we deal with those problems without burying you under
an avalanche of jargon. You won’t need a master’s in computer science
to work through our solutions. You won’t need a teenager on speed dial
to explain what a SCSI port is. You won’t even need to know that SCSI is
pronounced ‘scuzzy’, like the state of said teenager’s bedroom.
Instead, we’ll explain everything in (to use that hackneyed phrase)
plain English. And on each answer, you’ll find a brief ‘What can I do
about it?’ set of bullet points, that give you an overview of the potential
solutions before you dive into the full explanation.
As we said before, we don’t have all the answers – but we’ll give
you advice on where to find them if you come across a problem
