you will notice a difference but not necessarily as much as you think. Look in start - run and type msconfig then enter. Click in the startup tab top rightish and see how many boxes on the left hand side have a tick in them. I only have ticks in the virus checker, graphics card driver and firewall. Take ticks out and restart. When it gets going place a tick in the box on the left. If you take a lot of ticks out you are stopping many progs starting and running in the background which is slowing everything up.
