To enable your GTX 1070: Go into your BIOS/UEFI by tapping "Del" and "F2" when your computer starts up (just keeping mashing it until you get into the motherboard's settings). Then go to the "Advanced" tab and select "System Agent (SA) Configuration." In there, go to "Graphics Configuration" and set the following (from pages 2-24 through 2-26 of
your motherboard manual):
Primary Display: PCIE
iGPU Multi Monitor: Disabled
RC6 (Render Standby): Disabled
Then, shut down your computer, plug the monitor into the back of your GPU (i.e.
not the motherboard), and boot up your machine.
To make your motherboard deliver information to your CPU and GPU properly: Install all drivers
in the correct order, which
Intel describes as follows on its website.
Step - Install
1 - The operating system.
2 - The latest operating system service pack and patches.
3 - The Intel® Chipset Device Software (INF Utility).
4 - All other device drivers (audio, graphics, LAN, and so on). You can install these drivers in any order.
Step 1 - The OS: You've already done this.
Step 2 - Update the OS: Press the Windows key on your keyboard, and then type "Windows Update" to search for it, and open Windows Update. On the left, click "Check for updates." After the computer searches for updates, install all "Important" updates and any "Optional" updates you want.
Step 3 - Install the INF Utility: Go to
this ASUS website for your motherboard, select your OS (Windows 10 64-Bit), and expand the "Chipset" downloads tab. Download the latest "Intel Management Engine Interface" (IMEI) and "Chipset" drivers (be sure to check the date).
Because you need to install these BEFORE your other drivers (e.g. GPU drivers), uninstall your GPU drivers using Display Driver Uninstaller (DDU). Get the
latest version from this link. Run the program, let it restart and take you into Windows running "Safe Mode." Follow the prompts to remove everything related to Nvidia.
Restart your computer normally.
Step 4 - Other drivers: Download and run
GeForce experience form this link. While running GeForce experience, download the latest GPU drivers and do a "Fresh Installation" when given the option.
** Note that if your internet doesn't work, you may need to install your internet drivers, which you can get from the motherboard webpage I linked above (under Step 3). **
RESTART and try game again.
Good luck!
