The computer would not boot my XP drive (only one) this morning. No known changes were made prior to shut down. I could access the drive through live Linux disks and Free-Dos, so the drive seems okay. I finally ran the repair facility and used chkdsk to verify the drive was again okay. I then went to the install function and selected repair instead of a full reinstall. The machine has restarted with XP. I verified the properties and the bios setup to make certain that everything was normal. Present problem - Outlook can't open the default email folders. I can't get into www.microsoft.com (using IE6.0)or use the update manager with the message "The requested lookup key was not found in any active activation context". I'm using Firefox at this time to get onto the MS site. All the restore files were deleted during the repair, so I'll not even waste my time using that option in the future. I also ran a virus scan (auto-updated yesterday) and found no issues. This is an upgrade from 98 ( 3months ago) with all the online updates using update manager, with the exception of IE7 because of all the negative press it recieved. 1G of Ram & 1.3 AMD and plenty of hard drive space. I use my computer for work and not play, so there is no junk software on my system. 3 Questions 1) Is there any way at this point to avoid a full re-installation of XP and all my other software? I already lost a work day going through the first round. 2) Is there any common explanation for this sudden boot issue, even when the disk is clean by even MS analysis? 3) Is there a true full backup program for XP, that will not require re-installation of XP first to re-access the program. Thanks in advance,
