Unable to Enter Windows 8.1 Safe Mode after Screen Resolution Change

Guys! I went ahead and by mistake changed the screen resolution of my Windows 8.1 to 2568xsomething on my VGA 1024×768 display. Now it is giving me a change screen resolution error, The screen is black I cannot access Windows.

I read on Tom’s Hardware to go ahead and hold F8, that does, not work until I restart. How am i supposed to restart it, if I cannot see where the restart button is.

Also, I have a login in my motherboard, so I cannot hold F8, if I just press the power button to restart.

Help would really help.
