Windows 8 Fail Installation

I am currently working off a Windows 7 PC and am having issues with the installation of Window 8. It gets to the "Getting Ready 44%" stage and then the computer freezes. After restarting the computer to unfreeze it I receive a message of " Windows 8 installation failed." And it reverts my computer back to Windows 7. It has done this numerous times and I am becoming increasingly frustrated with this situation.
