Have to Reinstall Nvidia Gtx660ti Drivers After System Shut Down/Restart

I am having a very annoying problem. I purchased my computer 3 months ago and I have been dealing with this issue from the out of the box. The graphics drivers don't seem to be "sticking". Everything runs fine in the computer, but for some strange reason I have to reinstall my Nvidia drivers (320.49) every time I shut down or restart my computer. I've tried using previous versions but to no avail. It is a hassle and an annoyance to have to reinstall the drivers every time I shut off my computer; I usually keep my computer in sleep mode because of it. I have been looking into this for months and have yet to solve this problem.

My Computer Specs:
Processor: AMD FX 8350 - Eight-Core Processor - 4ghz
OS: Windows 8 (64 bit)
Graphics Card: Nvidia GTX 660ti
Motherboard: Gigabyte - GA-78LMT-USB3
Memory: 16gb

any help would be greatly appreciated!

    You can try this :

    Instructions for manually disabling secure boot:

    1) Power down the system

    2) Remove the NVIDIA Add-in card

    3) Boot the system using integrated graphics

    4) Enter CMOS settings. CMOS settings can usually be accessed during boot, typically by pressing one of F1, F2, F8,

    F12, or Delete (depends on the system firmware) Alternatively they can be accessed in Windows 8 as follows:

    5) Set Secure Boot to disabled

    6) If there is an option, set CSM (or compatibility or legacy mode) to enabled.

    7) Save the new settings

    8) Power down the system

    9) Install the NVIDIA Add-in card

    10) The system should now boot then install the graphics driver.

    * Note that not all existing NVIDIA based cards are capable of adding UEFI support. If your card manufacturer is unable

    to supply you with an update, you will need to operate in compatibility mode" (
