    Hello!
    I've got a strange problem with my Samsung notebook and 650M. The system ran fine until I decided to try new NVidia drivers.
    I did a clean uninstall (uninstall in control panel - reboot - uninstall in driver sweeper - reboot). After that I tried to install new drivers and got an error about no hardware. I thought "okay maybe this beta driver does not support my card" and tried to install the old driver from Samsung website, but it gave me the same message.
    I looked in Windows Device Manager and there was only Intel 4000 and no sign of 650M. I was like "" and ran AIDA64 - my card was there, under Display - GPU, along with Intel.
    I tried googling this issue but haven't found anything, the card is just missing from Windows. Can you guys give me a few pointers?

    Update:
    I found the card in Device Manager, it is listed as Unknown device and has status "Currently, this hardware device is not connected to the computer. (Code 45)".
    I also booted from a LiveCD and the card was detected on it.
    Any insight on this?

    Okay, I fixed it I guess.
    I deleted "PCI Express Root Port" device and readded it. Then unknown videocard showed up in Device manager and I've installed the driver.
    I guess a mod should close this topic, sorry for flooding a little on your forum :3
