Twice in the last two months my 8200 Dimension system has crashed with a \system32\hal.dll missing or corrupt" message. I can get to a recovery menu via a boot to the Dell XP CD , but after reinstalling what appears to be a lot of drivers, etc. Windows still fails to load with the same message. Is there anything I can do in the way of a system backup to protect against a complete reinstall of XP and the loss of my software configurations? Any help much appreciated.
