Maybe someday the XP forums "Ask a question" dialog will ask these questions automatically when a new thread is started so I do not have to ask them every single time. It might even be possible to resolve an issue in a single reply when enough information is provided.Please provide additional information about your system:What is your system make and model?What is your XP Version and Service Pack?Describe your current antivirus and anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc.Was the issue preceded by a power interruption, aborted restart, or improper shutdown? (this includes plug pulling, power buttons, removing the battery, etc.)Does the afflicted system have a working CD/DVD drive?Do you have a genuine bootable XP installation CD (this is not the same as any Recovery CDs that came with your system)?What do you see that you don't think you should be seeing?What do you not see that you think you should be seeing?Fill in the blank: My system was working fine until: ____________________________________________.Do, or do not. There is no try.I decided to save up points for a new puppy instead of a pony!
