need a bit help
 

What's the F button you push while your computer is starting up, that it will make you go to the screen that ask to reboot your computer from last time that the computer was working? thx, I just need this help asap, can a mod move this after I get a quick answer.

If you mash F8 whilst the computer is starting up it should take you to a screen with different options like "Safe Mode" etc. There might be an option for System Restore on there...maybe.

Yes, In Win98, 2k, XP, ME if you spam F8 while you're booting it will take you to a boot selection screen, where (Last Known Good Configuration) should normally be there.

Just need to hit it once.

If you only hit it once you need to know the correct time to hit it. Mashing it will make sure that you get to that screen.
