boot up time slowed

I have a Vaio E series
Core i5 2.40 ghz, 4gb RAM, ATI, Win 7 Home Premium 64-bit, 500 gb HDD, Norton 2010.
Months ago, it's boot up time was normal around 50-60 sec. But now, it started to slow,I went to msconfig>startup> and only synaptics pointing device driver, microsoft windows operating system, and catalyst control center are enabled.
But in services there are alot that are running(i hide all microsoft services)
adobe active file monitor v8
amd external events utility
apple mobile device
bluetooth service
intel proset/wireless event log
flexnet licensing service
google update service
intel rapid storage
intel management and security application local management service
norton internet security
protexis licensing v2
intel proset/wireless registry service
intel sample collector
intel management & security application user notification service
vaio event service
vaio power management
vaio content folder wather
vaio content metadata intelligent analyzing manager
vaio content metadata intelligent network service manager
vaio content metadata xml interface
vsnservice
vuagent
What can I disable? Or what should I do?
thanks

I've done this. But nothing

ok. i'll try this one

Ok, I've done it all.

Nothing changed. I think the norton internet security is the one which makes this slow. what do you think?

What should I do now?
