G751 - Windows Startup blank icons/Can't press Windows button

[Thrill4]

I've noticed that sometimes when you restart Windows, you can't press the Start button for awhile and some desktop icons are blank. You need to wait about a minute before you can do anything on the laptop.

Doesn't seem to happen if you turn the Laptop on from "cold boot". Done Crystal Disk Mark on both the SSD and HDD and both are reading and writing insanely fast (e.g. 7200 drive is at 120 MB/s) so I doubt it's an issue with the drives.

Any chance you could list what update you reverted so I can google the name and figure it out?

sorry I did not notice which ones reverted,this is a new windows install and only the second time I had run windows update,there was quite a list,nerver thought to do a screen print,sorry.

I don't remember which update made this issue, That's weird that putting every delayed services in automatic the problem isn't gone!

At this point if you don't find a solution and planned to upgrade to win 10 the 29th just live with the issue until then, the win 10 update will fix it anyway.

Okay so uninstalled all Windows updates and am back to the Asus factory Windows image without any other updates: http://i.imgur.com/VSCzgU9.png

It's still failing though (e.g. I can't search right away for files etc). I'll screenshot my services.msc and someone without the problem (or who fixed it) can compare to theirs, I can narrow it down.

services.msc pictures below from top to bottom:

Okay fixed it. Took me ages but done it. 🙂

CNG Key Isolation is the culprit. It's set to Manual Trigger when it should be at Automatic Trigger.

Ahh great to know i told you it was a services issue.. Glad to hear you fixed it

Setting the CNG to automatic trigger works perfectly for me charted on multiple reboots and not a problem since the change thanks to the person who started this thread and everyone that contributed 🙂

[antoine52200]

i had this issue, and i've never used the hybrid sleep mode in my life. Thoses issues happened to me on every cold boot and reboot!

Okay just an update on this. Done more digging and figured out what actually causes it.

CNG Key Isolation is not the problem, just a way for it to work. I asked on MS Support forums and was told this about CNG:

"CNG Key Isolation will not start, if the Remote Procedure Call (RPC) service is stopped or disabled.

If the CNG Key Isolation is stopped, the Extensible Authentication Protocol fails to start and initialize."

So first, I put CNG back to Manual and issues happened. I then looked at the Remote Procedure Call and Extensible Authentication Protocol services.

RPC was not running so I didn't touch it but Extensible was so I set that to Automatic and it works still! 🙂

It seems to be something to do with wireless security and public/private keys. Can't believe the storage of wireless keys would cause so much issues but there we go.

I have a solution for this issue!
(If you are using nVidia Geforce Experience)

I had this same issue, slow boot up, slow loading desktop (about one minute), with blanked out white icons
After some investigation, I found the problem, and the solution.

The latest version 2.5.11.45 of the nVidia Geforce Experience is causing this issue.
2.5.11.45 is so buggy, that 'RAID Bug spray" could not kill them all.
After I uninstalled the nVidia GFE, and than ran a clean install of the Geforce Graphics driver installer (- GFE) everything was back to normal.
The new GFE update seems to be causing some major memory leak issues!

If you would like to read more about this issue, here is a link below about this issue from the nVidia Geforce forum.
(Take a look at post 118)

Hope this helps my friend.
Good luck, and good gaming!
