i did a fresh install of windows 8.1(also have a new ssd). If you restart(not shut down) it hangs up on the windows 8.1 loading screen before u put in your password, but if you shut down turn the power off to the power supply hold the power button for a second to get rid of residual electricity, it will boot correctly and fast into windows..... Im befuddled i just don't know why it would do this.. Also as i remember if i put my usb thumb drive that has the install for winds 8.1 if i dont shut the power supply down adn do the power thingy it wont boot into that ither which makes me think it might not be the harddrive, one more thing i also went inot bios just a few min ago and loaded fail safe defaults any help would be really appreciated thank you all
