    Previously it showed Blue Screen every time I boot my Y460; few seconds after the Window Logo. No matter how many times I reformate, it still showing Blue Screen, indicating STOP 0x00000116 and atikmpag.sys error. Subsequently, I went into the BIOS and changed the settings on the graphics switchable to discrete graphics. However its getting worst now because there is no display (totally black with no background light) every time I on my y460. Hence I need assistance and solutions, thanks.

    Hello mate,


    maybe you can try thisfirst :


    1) try with another ram module (if you can of course)


    2) if you're able boot in safe mode, go to the Device Manager and uninstall the video adapter and then restart your laptop


    And please tell us what you got with these steps




    Thanks

    The stop error 116 is directly related to the graphics driver and/or the graphics processor. As you have reinstalled to try and fix the problem then it is highly unlikely to be a problem with the driver which leaves the most likely problem as the graphics chip. In most cases this would require a full motherboard replacement.

    If your fans are running at startup that would also rule out overheating which can also cause the same error. Even without the fan running or if it is very clogged up with dust it isn't likely to overheat so soon in the boot up process.

    There is nothing we can do from here to test anything when the system is failing to boot up so your best course of action would be to have it checked by a PC repairer.

    I don't have extra RAM to test with and the screen is showing nothing when is on, hence impossible for me to boot in safe mode

    Mark1956:
    When booting, my Y460 runs perfectly like normal except the black screen I am facing now, and the fan is running perfectly as I had cleared off the dust (little dust was found when I opened) Previously before I went into the BIOS and changed the settings from graphics switchable to discrete graphics, I was able to boot in safe mode but showing Blue Screen when boot normally. But after I changed to discrete graphics, there is no display (black screen). May I know what is the reason?

    Thanks people !!

    This is an extract from your computers specifications:
    So basically you have two graphics chips, one for general use and the other for high demand graphics software.

    I was just explaining the difference between integrated and discrete graphics.

    What I said in post 3 is the best advice I can give for the problem. As you have no screen output there is clearly an issue with the graphics(as is evident from the BSOD error code), we can't run any diagnostics without the graphics working so this needs a hands on approach.
