I bought Ideapad Z500 with geforce 740M with freedos. I installed w8 64bit and coudn´t install gpu drivers. when i start installing program after cheching it says something like "coudn´t install gpu because your hadware isn´t compatible". in bios it is set on "switchable graphic". I don´t know what else to do. Thank you very much for advice.

Can you uninstall your Intel HD drivers and install this Lenovo Z500 Intel HD drivers using this link: http://download.lenovo.com/consumer/mobiles/1hvh14w8.exe
After that, install Lenovo Nvidia Driver's for GT 740M here and see if it works: http://download.lenovo.com/consumer/mobiles/1hvg08w8.exe

Hi, i have exactly the same computer and had exactly the same problem. I was unable install drivers on W7 64bit, but on W8 i was able to install drivers version 320.49. drivers which come with laptop on cd didn´t work on W8.
