One of the computers in my one care circle has many computer issues. According to Circuit City, this computer has to be totally dumped and start from new. It is always recieving errors and the internet windows that are open closes frequently. Since I have added this computer to my circle, I have had a computer crash and an error message that states that there is a dirty file in the NTFS. My E backup drive has also disappeared. I am wondering that could this one problematic computer be giving my computer problems and should I remove it from my circle?
