Follow that thread and see if it rings a bell.
It seems I'm full of problems lately, I can't seem to reboot into safe mode! When given the option to reboot my computer it doesn't ask if I wan't it to be in safe mode or not. any help?
If my thoughts on your post are correct you are unable, by pressing the F8 key, to access a boot option menu. If this is so I have two options for you to try. Only the first option is safe.
If the system will boot to normal mode go to "start" -> "run". Type "msconfig", press enter. In the first window fill radio button "Diagnostic Startup". Click apply/ ok and reboot.
Or allow Windows to start booting then pull a hard shut down (turn off the power to system)(not the best idea as corruption of operating system can occur). Windows should then reboot to boot option menu
