About | Bleeping Computer |
Bleeping Computer® is a technical support site and a self-education tool for the novice user to learn basic concepts about Computer Technology. Our focus is to allow the novice computer user to be able to have a place that they can come and discuss computer/technology problems with their peers and at the same time have a rich resource in which to learn the "basics" about computers and technology.
We have found, with our extensive experience in helping users, whether they be family, friends, coworkers, or clients, that most technical support problems lie not with the computer, but with the fact that the user does not know the "basic concepts" that underlie all issues of computing. These concepts include hardware, files and folders, operating systems, Internet, and applications.
