When scrolling down the list of files the system stops, hesitates and slows down. So when trying to type in the characters of the name of the file I get to the first to and then the system beeps like I have done something wrong but in fact it just stopped looking for the buffered characters that I had typed. I have scanned for viruses and found none. The profile was just created last week. What could the issue be? The user is ready to go back to his XP machine.
