One of my resolutions this year is to learn something new so I thought learning to debug my computer would be rather useful. Does anyone know of any such courses? Is there even one? I don't want to write a programme etc, just to periodically get rid of all the bugs onmy computer and to understand what is going on. Right now, I do not know what to delete, whether the file is safe or not etc. Someone told me to do this every 6 months.
