Windows 10: My computer doesn't dedect my GTX 645 after Windows 10 Upgrade. Help!

I downloaded Windows 10 and started using it today. I saw a new update came out on Nvidia GeForce Experience. I started to download it. After it downloaded, I selected custom setup and it started setup. After a while, (2-3 mins, not that much) the screen is randomly gone black. I waited a couple seconds. Then... BSOD after all. *EekIt said DRIVER_IRQL_NOT_LESS_OR_EQUAL (epfwwfp.sys). After a couple researches, I found out its made by ESET Antivirus. I went on safe mode and deleted that file, then restarted my PC.*092 Everything seemed to work well. But... after I opened GeForce Experience, I saw my GTX 645 isn't updated because the setup buttons was still there. *Eek*ThinkI started the setup. After a while again, it said Nvidia cannot continue the setup. Then I closed it, went to the Optimize section and I saw that my system isn't dedecting my GTX 645.*Shock Can someone help me? I've been trying to fix this for a couple hours.*Sad*Sad


Sorry for my English, I'm Turkish.

NVIDIA GeForce GTX 950 Display Adapter is suddenly hidden in device manager

This graphics card is still installed, and is working (somewhat), because one of my two monitors attached is still working. The card has been installed on my Dell 8700 with Windows 10 since last November. Everything seemed fine until yesterday afternoon,
when I decided to upgrade my NVIDIA drivers from version 361.43 to 361.91. after that was completed, with no obvious errors, upon rebooting Windows, I had only one monitor working, and the NVIDIA GeForce Experience app no longer recognized that the card is
installed. That was when I looked at device manager, and found that there was no display adapter listed, until I did a View/show hidden devices.

Oddly, I then saw both a nonexistant NVIDIA GeForce GTX 645 and my NVIDIA GeForce GTX950 were listed. I uninstalled the 645, and restarted Windows hoping that might resolve the issue, but it did not - the GTX 950 is still 'hidden'.

The other thing that happened yesterday, earlier in the morning, was a Windows update KB3140743. Because that was a suspicious coincidence, I uninstalled that as well, and rebooted again, but still no resolution.

Any suggestions would be appreciated. I suppose the card may have failed suddenly, but this seems more like a Windows 10 problem.

Thanks, Myles

 

Uninstall ESET completely using the tool below and use native Defender coupled with MalwareBytes.

Uninstall GeForce Experience, you'll be better off manually managing your GPU drivers.
