Have a HP Pavillion a550e AMD 3400 64 bit system that worked fine
and then I installed SP2 and now whenever I do an install of a
program and a restart is required the system hangs and you must shut
down manually. Normal shutdown is not a problem. I have read on HP's
help forum that many AMD 64 bit users are also having the hanging
problem on restart after SP2 install. Does anybody have any
suggestions or additional info other than to do a system restore.
