xp hangs on sp2 upgrade

hi,

before i describe the problem, thanks again for all the help in restoring another computer which had a bad virus and malware problem.

my work laptop dell inspiron 8100 is having problems. while trying to update xp with sp2, the system hangs partway through the update, so we can't get the system update installed on tne machine.

in addition, when we started looking around, we noticed that the "help and support" feature won't open, it hangs trying, and then after we got to system restore, it doesnt work either

other than the problems listed, everything else works fine

for a start, i've attached the hjt scan for the laptop. any ideas what can be causing the problem?

thanks again,
