I downloaded and installed a trial version of NTI's Backup NOW 3.0. My first attempted full backup hung the system during the file compare. I was backing up my C: drive with 14 GB of files (it is a 60 GB drive)to new 80 GB freshly formatted internal hard drive. During the backup Windows kept warning me that the space on my target drive was low. When I restart WinXP Pro (administrative rights) it starts very slow. After I click on my ID to login the only thing that comes up is my wallpaper. No task bar, no sys tray, no icons, nothing but wallpaper. I can bring up the task manager with ctrl-alt-del. I did a hardware system check and everything checked fine. If I try logging in under a different ID I get the same thing.
