Why do I keep losing my computer settings? dlx8902007-01-08 00:53:47

First of all, I do not know much about computer.
Can anyone tell me why my computer settings (for example desktop arrangement) disappear once in a while? (Nothing saved in the hard disk gets lost.) Is it because of some type of virus?
Thank you.
