I'm about to ask a question on the main site, but after seeing similar questions and how they were treated, I decide to come to Meta first.

The proposed question is about my Ubuntu installation randomly freezing. There are quite a bunch of past questions about similar situations, offering all sorts of tips and solutions, some of which worked for others, but not for me. However, in the process of research, I came across this question that was closed because:

"This describes a problem that can't be reproduced that seemingly went away on its own or was only relevant to a very specific period of time. It's off-topic as it's unlikely to help future readers."

Additionally, when I go to the ask question page and tried to add a "freeze" tag, immediately I noticed the description:

Do not use. This tag is in process of removal. If your software is freezing then you likely need to file a bug, as freeze problems are usually off topic here and will likely be closed.

How come? Even though freezing phenomena are often hard to track down, they do happen and cause major annoyance, therefore I come here and seek assistance. Can I assume that if I post one such question it will be closed, even if I did prior research (i.e. what didn't work) and state those clearly in the question?
