It really depends on the question. If somebody wants Windows 7 drivers for an 8 year old laptop that hardly even has the specs to support Windows 7, or conversely wants Windows 2000 drivers for a brand new chipset... probably not a very constructive question. But consider this question about finding Windows 7 drivers for a particular Dell laptop. The question has almost 16,000 views, and is one of the highest ranked questions for anonymous user feedback, with +64/-4 "was this answer helpful" votes.
There are about 275 questions with the text "find drivers" in them. Of those, about 120 have accepted answers, which is almost 70% success rate with driver questions. This tells me that these questions are useful to somebody, but a lot of them are indeed one-off sorts of things - only about half of those with accepted answers (40% of the total) have more than 200 views, and a mere 15% have over 1000 views.
So there's some data to consider. What should we do about it?
One thing to do would be the "google test". If you can find the drivers in 5 minutes by checking on google or the OEM's website, then the question should probably be closed as "too localized", kindly give the user links, and remind them that they can find things themselves as easily as we can.
If the google test returns a lot of similar "I can't find drivers for x, help" sorts of pages - especially if said pages are on forums - then I think we should keep the question. Even better if we can solve the problem! This is a case where we can actually be a useful resource, rather than being redundant.
Another thing to point users to is the Community FAQ on "how to find drivers". The method I describe in that post of looking up the vendor and hardware IDs works very well for almost all computers I've ever had to find drivers for (which is a lot of them).
Basically, "Help me find drivers" shouldn't be specifically off-topic. It's a valid computer question. But we also aren't a driver database. For specific "help me find driver" types of questions, it has to be a judgement call on whether the question should be kept around, or is too localized to be useful. If you aren't sure, then feel free to discuss with other people in our general chat room or the ask a moderator chat room. Try the google test. With this specific case, I think we should error towards helping people rather than shunning them, but that can include pointing them towards our existing resources (like the community FAQ mentioned above).
