Actually, I have my hard drive back in my laptop. From July 3 through late yesterday I had a loaner hard drive. On July 3 my laptop repeatedly froze as soon as I entered my password. The university Help Desk staff worked on it all day. They replaced the BIOS. They ran diagnostic and repair utilities. A dedicated technician stayed late with me to isolate the problem. By swapping hard drives between two identical machines we were able to conclude that the problem wasn't in my laptop hardware but in one of the many drivers and applications that launch at start-up. He was able to move the files I most needed to my network storage, install the other machine's hard drive in my laptop, and move those most needed files to that drive. I had to use the less-than-friendly Outlook Web interface and I discovered just how much I depend upon customized tool bars, shortcuts, and my Merriam-Websters 11th Collegiate Dictionary. It was a very tedious process for a technician to identify the offending software and delete it from start-up.
