Many times when a problem crops up the advice is update your drivers.
But, why? If you have a computer that's worked for years with all the drivers on it why does it suddenly need a driver update? It's not like you or a machine that parts wear out. What was written in a driver stays. It doesn't rust, get corroded, overheat, wear out etc.
Just one of those questions that has bugged me for years. (first started programs by writing a database program on a Commodore 64)
