Best Free Technical Support Sites

AskMeHelpDesk is a Web site that pairs experts and novices to answer and ask questions. There are hundreds of topics, including many computer-related ones. The computer sections are quite active and I got answers to our test questions within a few hours.  Take the strain off your help desk and get your users to check out this excellent free resource.
Techie 7 (formerly D-A-L Computer Help) This a forum based Windows help service. It's quite active with responses to questions often posted within a few hours. The "Spyware, Adware, Viruses and HijackThis Logs" section is particularly active and the answers posted both helpful and sound. The "Hand Held" and "Web Design" sections are currently a bit thin but that does not distract from the overall excellence of this free site for general Windows support. Registration is required to post a question but this is a simple and speedy procedure.  Well worth trying.
Help.com is a free tech support service from CNet.  There are plenty of online resources to help you, drawn from a variety of sources.  Some of these are on the help.com site, some are elsewhere. Included in the latter is a question and answer service that links to gives you an easy interface for the Usenet support newsgroups, although to use this service you must register.
Suggest A Fix   This is a free forum where users can post problems in the hope that another forum member can help. The available forums cover operating systems, general computing, the Internet and security with many subdivisions under each category.
The forums are not the busiest we've seen but almost all questions attract good quality answers. Our 3 test questions were answered very promptly indeed the solutions provided and were of high quality.
Like many other forums, a few dedicated individuals seem to provide the bulk of the answers so you might find the quality of the answers varying day to day according to who's available. This reservation notwithstanding, we couldn't fault the service we received.
About Guide on PC Support Here you'll find an excellent portal site for all PC support issues.  The information presented is thorough and comprehensive. They have a forum area where, after registration, you can post messages to other users free of charge. It's not a particularly active forum, with only a dozen or so messages a day, so you may have to wait a while for a response. We did however, get answers to our problems and the correct answers at that.
Virtual Dr This site forms just part of the huge Internet.com group of sites. They offer a pretty good set of online resources plus a well-used forum area where you can pose questions to fellow users. Registration is required but is free.
