Please HELP Slow boot up 1 month after CSC installed


I installed the CSC about 1 month ago on a PC in my office running Vista - I waited a couple weeks to see how good the program worked - after being satisfied with its performance I installed CSC on another computer running XP in the office. Again I waited a couple weeks and again was very happy with the results. I then installed CSC on another 3 computers in the office all running XP. Immediately after installing CSC on the last computer I started having boot up problems. It would take at least 30 minutes before the computer would function normally and come “on”

Now all except the two computers running Vista are extremely slow to start. (30 minutes to 1 hour)
So far I have used the restore function in CSC, uninstalled CSC, and used windows restore to an earlier date nothing seems to help.

Can someone help me out?

Thanks in advance
