I purchased a dell Dimension 3000 desktop system 10 months back. It was up and running till a few days back, but it is giving me a lot of problems since last 3-4 days. My system was under warranty so I called the Dell Technical Support to fix my issue. The agent seemed to me an expert and probed me step by step about my system's issue, he told me that my network card is not properly installed, but in between the call got disconnected and I did not wanted to call again and wait in the long call queue to get my call answered , I remember that he had asked me to shut down the system and drain the flea power. What does that mean?
