  1. After updating my bios from 1.09 to 3.05 my GT 750m stopped working. Nvidia drivers can install but once installed none of the features work. No Nvidia control panel and all of the tabs in Geforce Experience except for the drivers tab are grayed out. The drivers tab does not recognize that the driver has been installed and the option to update the driver is available. Downloading the update and installing it leads to the same issue. With the tabs being grayed out and the driver tab showing that I can update the driver. When I look under Device Manager the 750m has a little yellow triangle and in the properties it reads a Code 43. I have used Display Driver Uninstaller multiple times to do a fresh driver install of both Nvidias drivers and Lenovo's Nvidia drivers. Those lead to the same issue. I can't reinstall the operating system because during the install phase the computer blue-screens if the discreet card is enabled in the BIOS. Right now I am running in UMA Only mode. On startup when using the discreet card the computer sits at a black screen for about 2 minutes until the computer switches to the IGP. So after a completely fresh driver install the card still fails. This only started to happen once I upgraded my bios. (I should have stuck to the "if its not broken don't fix it" rule). I upgraded from v1.09 to v3.05. So now I am wondering if it is possible to downgrade my bios from 3.05 to 1.09 or if that jump is too large. I looked in the bios mod thread and want to use the provided files to downgrade my bios without installing the modified bios. But I am wondering if I will have any issues with the version jump from 3.05 to 1.09 being so large. If that is the case then can I jump from 3.05 to 2.07 then to 1.09.
