How to revive an old PC
ONE OF MY INTERESTS is in recycling and reusing older computers. I regularly take such doorstops that clients are discarding, upgrade them with some marginally newer bits, put a lightweight OS and apps on them and give them to impoverished - or just tightwad - mates. With the right choice of software, even a five-year-old computer can be a fast, responsive machine with bags of life left in it.
For example, if they know enough to want Windows, I generally advocate Windows 2000 as a good version.
For people with little to no computer experience - or no spare cash at all - these days I recommend Linux. For novices, it's as easy to use as Windows - indeed, it looks and works in much the same way - but they're safe from all the nasties out there.
For the poor sod setting the thing up, Linux is quicker and easier to install than Windows.
