thcri,
How did you determine which were the "troubled programs" on your laptop? As per my earlier post in this thread, I had same problem on my laptop. Now up to 6 installs of SP2 on 6 different computers, and that's the only one that was problematic. That computer was purchased w/ Win 98SE (awful version /forums/images/graemlins/frown.gif). Eventually, upgraded to XP, and changed file architecture from FAT to NTFS. Any suggestions as to where to start to narrow down the cause of boot failure after SP2 install?
