    Expert Answer
    If at that point you're still experiencing freezing issues, I would say as a precaution, especially if you do not have a backup, to turn your computer off completely. Because when you do experience slow performance issues sometimes—not to say every time—but sometimes that can be an indication of a hardware failure, specifically the hard drive, or even possibly the memory.
