No Direct3D after Windows 10 update

[Dagesh]

After the latest Windows 10 update my GTX 1050 sends me to blue screen (version 388.13 of drivers). I used DDU and installed version 385.69. The computer no longer goes to blue screen but I found the following issue when trying to run NWN2:



Help is appreciated.

Did you get the graphics driver direct from NVidia?

Try reinstalling the DirectX runtimes.

That's a good point. Yes I definitely did that.

This seems to have solved the issue. Thank you for the link. My Google-fu failed me but yours succeeded.

After a restart, it's not working again. I'll keep poking it. Thankfully I have the integrated video card so in a pinch I can still play. It's just not optimal.

edit:
So I disabled the video driver, reinstalled the directx9 stuff and re-enabled. That seemed to allow the video card to once again have direct3d enabled (checked by running dxdiag). Running dxdiag a second time (no PC restart) showed direct3d as disabled. Repeating the disabling, installing, re-enabling seems to allow the direct3d for a time. Not sure what is turning it off.

Edit 2: Simply disabling and re-enabling seems to flick the direct3d switch back on but after a time it goes back off. Not sure what the issue is.

Edit 3: If I disable then re-enable, run NWN2, then check dxdiag after some time, the direct3d remains enabled. Hmm.

Maybe your video card is bad? You should be able to do DX9 easy with that 1050.

I FINALLY figured this out.

The issue: In dxdiag, under the tab of the particular video card, Direct3D DDI: was showing as none in the Drivers window.

The solution: There were a lot of threads about messing w/ regedit. One said to update bios. That's the route I took. I went to the laptop maker's website, found my particular PC, found both the newest bios and the utility to flash the drive from within Windows 10. Unzipped everything into new folders.

Flash utility was installed.

I ran the flash utility, found the bios file I downloaded, and it went from there (restarting, installing, etc.). Now we're right as rain!

Thankfully the card is fine so far as I can see. Whew!

The question remains, what messed it up? Also what is DDU?

All I can figure is the latest windows update did something but I can't put my finger on the real cause. DDU is Display Driver Uninstaller for a clean display driver install/update.
