The following boot-start or system-start drivers failed to load:
I ran CHKDSK /F from safemode (which, of course, ran after re-booting).
I have not changed ANY hardware or connections (out of money for now (:-} ) and a MB change is enough to make me keep everything else stable.
PS. While I waited for the new MB, I removed the IDE drive (which was ONLY used for backup of files on the SATA, not whole system) and put it in another XP PRO machine to be able to continue working with the backups.
All drives are formatted as NTFS.
Any hints you can give to help determine my problem would be gratefully appreciated.
