I am not very computer literate, so please forgive any lack of technical details in this post, but I really need some help. I have an HP desktop computer with Windows Vista home addition installed. About 3 weeks ago, my wife did a Windows update and received an error. I do not remember what she said what the error was, but it seemed to refer to a lack of disk space (we have lots of music and movies on the hard drive). I began moving files from the hard drive to an external MyBook drive and had several cut/paste jobs running when the computer froze up. As a last resort I did a hard reboot and the computer froze again. It has done this over and over. I cannot boot in safe mode either. I do not have a boot CD. How can I get past this? Thank you so much for looking past my lack of technical knowledge.
