OK, here’s it simply, the things that can slow down your browsing, assuming you have broadband and it’s running OK.

- virus software such as Norton, firewalls etc.

UNINSTALL Norton.  It’s just rubbish, it slows your PC down dramatically.  I recommend AVG Free (which is free of course) and just use the firewall built into Windows XP.

- spyware

Remove spyware with a VARIETY of programs – Adaware and Spybot Search and Destroy are the main two.  And they’re free.  Also delete your cookies in Internet Explorer

- tool bars

Remove google toolbar etc.  They just slow things down.

- less than 2Gig of free hard drive space on drive C

Small cache means the PC will run crap in general – make sure you have at least 2gigabytes free.
