Hey boo, I used this guide Here. When my GTX980 failed to install drivers I followed this. Now, this isn't a good solution but yet again anything at this point would help
Also, you can try to install the drivers from the GTX website. I did this when my GtX970 decided to uninstall the drivers. Right here The file you download has a setup.exe that you follow and it should install it for you.
EDIT: Since you have windows. You can see if your Laptop is reading that you have a GPU. So what to ensure of that you can type into your start menu "dxdiag" and hit run and click onto the "display" tab.
