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
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
