the idea itself is not bad. To ask a new question, i would suggest that you have to pick your devive and a description of your problem from a list.
This way the forum could show matching already answered problem-device combinations.
And you can only post a new question if your device question combination is not in the list or you checked a box that answers already given doesn't fit.
As this thread is going to be moved to beta anyway i have another suggestion, the growing number of unresolved questions.
A whole lot of the questions in unresolved are IMHO properly answered, but the one who asked never came back or just forgot to accept the answer. This way they are still in unresolved and you have to dig for really unresolved questions.
So i like to suggest that answered but not accepted questions stay in unresolved for, lets say, two month.
After that they change status to orphaned and after another two month the answer gets auto accepted.
Before the answer changes status the user should get a e-mail to log in and check a box to keep his question in unresolved for another two month.
I like to help people to repair their stuff, where to find information how to do it or even what might be the problem.
The unresolved questions is a good place to find unanswered questions or answers that might not fit.
What i don't like is to dig in IMHO properly answered questions of people who doesn't seem to be interessted in getting an answer. Because some questions are still in unresolved for nearly half a year and if these questions are not answered the way the user want's to after that time, i have to say sorry, there is no other answer and move on.
P.S. Kyle, if the Server issue on beta is resolved i can edit this post and open a new thread with my last suggestion.
