Safe mode business

My computer froze and wouldnt respond so I held down the power button for about 5 seconds until the computer shuts down. So I waited for about 5 minutes and rebooted my computer.
A screen came up, giving me different safe mode options or start windows normally. I used the arrows key to use Safe Mode. My windows started to boot up but then it went back to the page with the options for different safe modes. I read online where if you enter safemode and then you hit F8 at the correct timing it gives you an advanced list. So I used that. Once I get to the windows advanced list a blue screen came up that said a problem has been detected and to retsart my computer, select safemode, hit F8 and then select Safemode again under the advanced list. When I did so, it took me back to the screen again with the safe mode options.
