This is just a basic guide to getting some unnecessary programs starting up to be disabled and defragging your HDD. Just to prevent some lag
First off download these tools
CCleaner
http://www.piriform.com/ccleaner/download/standard
Defraggler
http://www.piriform.com/defraggler/download/standard
Run both setups and follow the on screen instructions
once finished run CCleaner and you should see this
Click where the arrow one is 1 is on
then 2. on 3 are the programs that start up. disable ones that you see fit, dont delete just disable
Defraggler is self explanatory, use it when you know your going to be away from your computer for some time.
hope this helps
