If you can boot into Safe mode, uninstall the critical updates you suspect and the .Net Framework and see if that at least gets you back to where you were before the problem.
I guess you don't use Restore points, did you you use an earlier version of Drive Image?
If so, if you had image files saved and have a DI CD, boot from that and restore the saved image file.
I tried using DI 7 with the .Net Framework and had nothing but trouble... system booted slow and creation of image files took 20-30 minutes and then wouldn't properly restore... of course I use 2 SATA drives in Raid 0 and have no IDE drives, so maybe that was why it wouldn't work right.
I had to go back to using DI 2002 for backups.
