A+: F8, typical problems and best choice for startup options

There's only a small window of time available to press F8; it’s right between the BIOS and when the normal operating system boots. Press F8 repeatedly right after the BIOS POST begins. It is important to note that the Last Known Good Configuration option will only be helpful before a successful logon occurs. After a user logs on, that becomes the last known good logon. It is recommended that you attempt to repair a computer with the Advanced Boot Options before using Windows Vista’s System Recovery Options, or Windows XP/2000’s Recovery Console. Now, here are some typical situations:

Then, update that driver or remove its HW device to restore the system to function.
