Computer Problems
All computers will encounter problems (usually software related) at different times. There is a forum managed by PC Advisor that I have used and contributed to on a number of occassions.
The forum is free to join (although you will need to register and create a userid) and you can review previous topics to see if they answer your question or post a new one and wait for other forum members to post their response.
They also have a section for less experienced PC users and its always worth stating your experience level when you post a new topic.
