Windows 10: Windows won't boot after adding second graphics card or enabling iGPU

Here is my system info:


Windows 10 pro 64 - ver 1809 - build 17763.195

i7-8700

Asus Prime Z390-A motherboard

64GB (4x16) Ripjaws V series DDR4 2666 CL15

2 x ADATA XPG SX6000Pro 512GB PCIe Gen 3x4 M.2 2280 NVMe drives (RAID 1)

PNY Quadro P2000 graphics card

PNY Quadro P400 graphics card


(all drivers and BIOS are up to date and installed)


If I only have one GC installed (either one, it doesn't matter) in either the x16_1 or x16_2 slot on the motherboard the system boots fine and sees the card and my monitors. If I add a second card, the system will try to boot. I get the spinning dots, but they stall out (two to three times) and then I get a blue screen that says that I don't have a bootable device. If I power off then power back on and inter the BIOS, my drives do not show up. If I then power off again, remove one GC, and restart, the system boots fine.


I have also tried to just enable the iGPU along with a single GC and the same thing happens.


I have worked with Asus, PNY and Nvidia and everyone says that their hardware is good. So, I'm down to a possible windows problem.


Is there something I need to do to make two GC's work in Win 10?

graphics card problems

Hi,

Your computer makes a noise or beeps from your internal speaker because it failed to detect the graphics card. What we can suggest is for you to try cleaning your graphics card with a pencil eraser. Here are the steps below:

• Turn your computer off.
• Pull out your video/graphics card.
• Rubbed the cold contacts with soft pencil eraser.
• Connect your video/graphics card back to the computer.

Kindly note that this is just a temporary fix. If the case still continues, I suggest that you contact your graphics card's manufacturer.

Let us know how it goes.

 

Adding graphics card - system refuses to boot

Hello Chris,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

From the description provided, I understand that Windows is unable to configure the drivers for the external graphics device.

To be able to assist you better, let us know if the device you are referring to is connected via USB/PCI slot.

Also, let us know the exact error messages or the notifications which you receive during

• System notification prompting to use Device manager.
• At reboot.

As an initial recommendation, I suggest you to disable the internal graphics card adapter from Device Manager and then try to install the drivers for the new graphics card.

To do so, right click on the Start Menu, find Device Manager
and open. Locate the graphics device in the device list, right click on it and select disable. If it still does not help, uninstall the drivers for your internal graphics card and then check again.

Write to us with the updated information for us to be able to assist you better.

Thank you.
