The PC in question is a mystery machine. It could be suffering from the OS being damaged or the old IDE DMA bug.
There are some other 100 reasons but a damaged XP OS is not a sure thing to repair.
There was some Microsoft FEEDS Sync app but why would we need this?

The repair/install procedure by booting the program cd restored my non- operative xp computer (Probably disabled by a virus). After performing an ipconfig /flush dns and ipconfig /renew the computer went from being very slow to moderately slow. The computer is still not very useful.
Usually when I invoke a program, I get a dropdown window stating: "Microsoft feels Synchronization has encountered a problem and needs to close. We are sorry for the inconvenience. If you were in the middle of something the information you were working on might be lost.
Please tell Microsoft about the problem."
Can anyone offer a clue what is going on?
Thanks.
