Why does my y510p crashes when I play DX11 games?

[PortaDF]

So, I bought a Lenovo y510p to my GF for 2 or 3 years ago, and since a year it continously crashes with everything what uses DX11. The machine is well cooled, I'm pretty sure it's not the temperature that causes the issue. Everything under DX11 is just works fine. She played Borderland for 10 hours without any FPS drops. I'm metting mad about it.

I've tried almost all the possible solutions all over the web, please don't make me list all of them. (Regedit TDRDelay...etc, Afterburner over and downclock, system reinstall, DX reinstall, SLI removal, SLI reinstall, Driver downgrade, driver update, I even bought a brand new cooling system for the notebook however it's not the temp.)
The machine has two GT750 in SLI. I'm pretty sure I don't have to introduce it to you guys.
So if you can tell anything I've missed, I'd be grateful!

Your GPU doesn't support DX11 according to NVIDIA's site.. Look here: http/www.geforce.com/hardware/technology/dx11/supported-gpus

if it a 750M, it support directx 11 also

try using older driver for older hardware, or just use the one from lenovo
