Laptop's graphics card not being detected

Hello all,

After experiencing a crash recently on my Toshiba Qosmio x775-q7272 laptop, I noticed that all my games were running much slower. After some investigating, I discovered that my NVIDIA GeForce GTX 560M graphics card is no longer being detected - it doesn't show up under Display Adapters in the Device Manager, and when I try to open the NVIDIA control panel I get a message saying that "NVIDIA Display Settings are not available: An NVIDIA graphics card was not detected in your system." I went on the NVIDIA site and downloaded the latest driver, but it refused to install, saying I lacked compatible hardware. My BIOS is updated to the latest version. I need help! Can anyone tell me what to do to remedy this?

    In your BIOS, is there a setting to switch between the iGPU and Nvidia?

    I could discern no such setting in my computer's BIOS, no.

    If the card is removable then you might need to take the laptop apart to physically inspect the connection between it and the motherboard.

    The other possibility is that the GPU has died. If it is removable, the good news is that you can replace it.

    Check this thread:

    one person suggests trying to reset the CMOS by removing the battery for at least 10 minutes.

    From looking at this pic of a X775 motherboard from an ebay post, it is a removable GPU. That long slot on the top left is where it goes.


    Thanks for all the help. I tried removing the battery for 10 mins, but it had no effect. I'll try opening up the laptop to see what's what inside when I have the time.
