    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. It 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. 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. I 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. Can someone help me? I've been trying to fix this for a couple hours.


    Sorry for my English, I'm Turkish.

    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.
