Hi, i am building a X99 -WS ASUS motherboard with GTX1080 EVGA. Everything was going fine, HW, until I tried to install the NVIDIA drivers. Now I dont have POST any more and see a lit up LED (DIAG_VGA), indicating something is going wrong with the GPU. The QCODE (two hexadecimal code on the board) shows code 62 which is 'installation of the PCH runtime services'. My PSU is a 1000W.

Update: just passed code 62. I removed the PSU cables to the GTX1080 and reinserted them. Now the Q-code is A2 (IDE detect). Stuck there....

That kinda sounds like BS, it shouldn't matter really.
Did you tell them it was stuck on IDE Detect?
Does it worth without the GPU installed?

Are you sure the 1080 works? have any friends or other systems you can test it in?

My board does not have an onboard video. I ended up buying a cheap video card. Using that as primary and 1080 as secondary it boots and goes all the way to AA.

If you can get into windows with the cheap card:

If you have graphics or driver issues, one of the most common fixes is a clean uninstall and removal of your graphics drivers.

To uninstall your drivers, first download and run Display Driver Uninstaller, and follow it's recommendations of booting into safe mode and ect.
(This is a direct download link so you don't grab the wrong version)
http://www.guru3d.com/files-get/display-driver-uninstaller-download,20.html

You'll download a compressed file called "[Guru3D.com]-DDU.zip"
Right click and choose extract.
Go into the folder and run the DDU v##.##.exe
This will extract more files to this folder.
Run Display Driver Uninstaller.exe
Choose Yes when it asks you to boot into SafeMode.
After you've rebooted into safe mode.
When DDU comes up, if it hasn't selected your GPU manufacturer (Nvidia/AMD/Intel) then choose it from the drop down list
Press the Clean and Restart option
If a window comes up asking to disable the Windows automatic installation of display drivers click yes.

After (or before removing the old drivers, just put the new ones on the desktop or somewhere handy) rebooting back into Windows, manually download the latest drivers from Nvidia or AMD, don't use auto detect, choose you GPU model and OS from the drop down lists.

Thanks for this. I will try this... One question, my cheap card is also an NVIDIA card, so when I uninstall drivers I am also uninstalling the cheap card driver too, right? I am asking this because in the many attempts to fix this I realize that the driver installation executable is the same for both the cheap and the 1080 card. Thanks!

Yeah, but Windows has built in "basic graphics" drivers for like, well opening up windows and downloading the right drivers. So you can run without the real drivers, and the above will clean up any possible bad Nvidia drivers.

It's possible the GPU went bad though, but EVGA has a pretty good warranty.

If they're both hooked up, can you actually use both once you're in windows? Or like swap between them.
