first off in the bottom right hand corner of your computer if you see alot of icons start up there when you first start your computer then this is for you if you dont know already how to get rid of em.
Press your Start Button (bottom left) and go to "run"
now type in: msconfig
now you will get a box that pops up and will tell you bunch of stuff dont mess with anything else other than what I tell you otherwise you could do something really bad (possible) go to your "startup" tab on the top right of the screen where it usually is and click it.
Now you will have a closed in box with bunch of filenames n addresses and more boxes with checks in them. Now if your like me you dont want anything startin up when you start you computer up or while your even doing anything cause it slows you down. Now unless your like me right now 1 have 1 thing starting up when my computer starts up and thats my settin for my overclocked vid card. But other than that uncheck every box and then hit apply and ok. Then window you were jus in will now close and ask you if you want to restart or wait till later to restart.
Either way when you shut it off and then turn it back on the settins will kick in
