if you have either an internal or external drive to image to do it. then if the drive is internal shutdown the system and remove it. then you can wipe c without any worries. a bit of advice never keep anything ob c that you cannot afford to loose including your doc's. you have the ability in the windows to locate your doc's on another drive. by doing this and as long as you do regular email backups the worst that will happen if you have problems with c is that you might loose a few pieces of email.
yopu also have the option to let us know what errors you are getting. this is a forum for fixing windows problems after all, and we would not have access to your files.
