When was the last time you *had* to do a clean driver install?



That is, you had a problem, tried updating drivers, the problem didn't go away, so therefore you responded with a clean driver install (whether you used some third party tool or if the driver install package came with the option), and it fixed the problem.

I personally can't remember ever having to do it, and I wonder whether the people who advocate clean driver installs generally do it as a precaution, or they do it at the same time at least one other technique to fix the problem (such as the actual driver update fixed the problem, not the fact that it was 'cleanly installed'), ergo they don't know which tactic resolved the issue.

Just curious.
