Every day the same questions get asked over and over again. I believe that this is mostly due the poor search results provided by the search engine. By default the search engine searches entire threads for your keyword, lists any thread that has that keyword, and lists them in order of the thread which was most recently posted to. Many people have there hardware specs in there signatures, so if you are searching for a common piece of hardware you will get lots of threads that have absolutely nothing to do with your problem.
However, there is a way to get useful results from the search engine. In the menu click on the search button and click on advanced search.
Now click the drop down arrow next to 'Search Entire Posts' and change it to 'Search Titles Only'
Enter your search in the box and press enter. That's all there is to it. This should provide some meaninful search results. Please let me know if this gets you better results.
