Nvidia Optimus and black screen in some apps

Hello everyone. I’ve got a problem with my laptop which can be easily described as: “Some applications won’t work on my discrete videocard, showing black screen”. And I even know a solution: “Reinstall your Windows”. But still, before I’ll do this, I wanna try understanding what caused my issue.

So, I’ve got a laptop: Lenovo ideapad Y580

Code:

Intel Core i7-3610QM (2.3Ghz/3.3Ghz) (http://goo.gl/JqP3E7)
Nvidia Optimus:
- Intel HD 4000 (http://goo.gl/swtRgP)
- Nvidia GeForce 660m (http://goo.gl/4H21OM)
8Gb DDR3-1600 / PC3-12800 (2х HMT351S6CFR8C-PB)
Windows 10 x64 Technical Preview Build 14390
Intel driver - 10.18.10.4425
Nvidia driver - 353.62

• A few month ago I faced a problem, my Adobe Lightroom started looking like this:

Lightroom is using my 660m to accelerate its performance. If lunched on w/o acceleration or on Intel 4000, all is ok, but on 660m I’m getting black screen.

• Same problem with recent System Shock demo. On 660m I’m getting black screen, while I hear sound and can press buttons.

• And same thing in latest 3dmark:

Just black screen and possibility to press buttons.

But other games and applications work just fine on 660m. Even Lightroom worked perfectly earlier this year.
I just don’t know what has changed in my computer.

Things I’ve tried:

• Delete Nvidia driver and install one from windows updated
• Install latest Nvidia driver from official site with clean setup
• Change build of Windows (its easy since I’m sitting in TH program)
• Update Intel driver

Nothing of this helped…
Any advice?

 

Have you set the programs to run on the nvidia card in the Nvidia control panel?
