Hey everyone! I am the proud (slowly dwindling to not-proud) owner of a Lenovo y410p. However, I've had some issues. I sent my laptop in for a repair on the manufacturers defect where the laptop's case rips open on the left hinge. When I got it back, my 750m no longer worked. It states Code 43. What's weird is it sometimes will work, and then the next time I use my laptop, it doesn't. I have tried using it on Windows 7, 8, 8.1, and now 10. All have this issue. It's usually on Code 43, but once in a blue moon it works fine. What can I do to fix it? I tried reflashing the 3.05 bios, but that didn't work. I have also tried (many times) uninstalling the driver and reinstalling it. Any help?
