I could be wrong, but I believe it will delete your runtime. Copy it to a different folder to save it. it will also delete you library preference file. if you use external runtimes you'll want to copy that too. You can find that  in C:Documents and Settingsyour windows user name hereApplication DataPoser 7 and it's called LibraryPrefs.xml

Now the bad news: with all that your computer is doing, you might have a virus or some hardware in your computer might be going bad.  I'm no expert on computers so I might be wrong and I'm sure one of the gurus will be on later and correct me if I'm wrong, but you might want to back things up just in case.
