COMPUTER GEEKS!!! Need Windows 7 Startup HELP!!

GEEKS:

last week, i finally got sick of my computer being so damned slow (even after running defrag, cleanup, etc) so i went into my Toshiba bulletin board (i have a Toshiba Satellite laptop) and there was! a message that said that my computer might run faster if i made some changes to the startup menu.

it gave me 3 choices: 1. run only basic processes at startup, 2. restore to default, 3. customize.

so i was thinking "ok i'll choose basic (choice 1) and then enable applications/processes as needed."

WRONG.

now, my laptop (i'm on my backup laptop right now) won't allow me to do anything but turn it on and go to Windows!!! i can't access the internet, nada.

so the fix is simple, right? go back to where i was and click 'restore to default.'

PROBLEM: NOW i can't figure out where that startup menu thingy is that gave me those three choices!!

i've LOOKED and LOOKED and LOOKED. i looked in the "Toshiba Bulletin Board", i've searched 'startup' and NADA. NOTHING.

for the life of me i can't find that menu that gave me the 3 options.

HELP!!
