I decided to do a routine format, using the standard NTFS format option (not "Quick"). At about 83% the computer rebooted. Is this a hard drive problem?
I usually go with the NTFS quick format, and I eventually did this time, but is there a specific reason why the PC would crash in the middle of a format?
Windows appears to be setting up fine for now, although I am puzzled as to why it crashed earlier.
