So Lenovo y50-70 (i7 4720HQ, 8GB Ram, Nvidia GTX 960m). Two days ago, when I started it, just gave a bsod after a few minutes. After a few restarts, it remained the same. As the bsod referred to the nvlddmkm.sys, I uninstalled the video card's driver, resulting in frozen screen in a few minutes after starting the computer next times, just like the bsod. So I reseted the Windows with keeping my files, as I could not completely reinstall a new windows, because not at home a the moment. It fixed the freezes, but then I just saw, I'm getting Code:43 (=Windows has stopped this device because it has reported problems) for the Video Card. I have updated the BIOS, and used Display Driver Uninstaller before I reinstalled the driver. Does it mean, that the video card is no longer functional? Or maybe, the complete reinstall with formating the whole hard drive might has some chance to fix the problem? Sorry for the long detail, and Thank you very much in advance!
I have Lenovo y50-70, is it possible to replace just the video card, as it seems to be broken. And how much would the new one be?
You need to use the Lenovo driver for the gpu. When pc makers incorporate other 3rd party devices they also have a modified drivers because they can choose how much RAM to give the gpu and they can alter the firmware for the gpu in other ways, so basic windows drivers are not recommended, unless Lenovo say so. Drivers might be altered quite a lot for a TOUCHSCREEN. Use your lenovo updates software to get the best one. Below is example of what i mean as clearly Lenovo do have specific nvidia drivers for that range of laptops, but you should use lenovo update to get yours.
Laptops have most of their parts integrated, you can't just replace them.
What's going on was probably a driver issue, not a hardware issue.
I'd try starting the computer in Safe Mode and manually re-install the driver from there.
If the laptop can move around and function fine in Safe mode then it's likely to be a driver issue.
Sadly, NO you can't replace the video card. The GPU is soldered directly to the mainboard.
