A long, long time ago I worked for a local (and now defunct) computer manufacturer. I worked almost every position the company had to offer, but one of the more adventurous was “bench tech”. A bench tech is a computer technician who is tasked with diagnosing and repairing computer problems, hardware and software. Fixing hardware problems is relatively easy and relatively quick: find the parts that are malfunctioning or damaged and replace them.
Fixing software isn’t always that easy. One of the best questions to ask in this situation is “when did the problems start?” Generally speaking, if you can roll back to just prior to this date, the problems will be resolved – so long as you have a backup that predates the problem, and data backed up elsewhere.
