I had 580m, all driver failed to install . Recently purchased 660m , also unable to install any driver or all drivers fail during installation even after I remove the driver signature check on startup , my m15x, just does not like new gpus . I got sick trying the drivers from laptopvideotogo website , none of them . All sellets on ebay are telling that they provide drivers remotely , the fact is that none of them can make it work on win 8 64 bit and keep people lying that they can upgrade the old alienware with better gpu . I can bet 95 % of all video cards sold ended as crap burned with bad drivers . If someone in this forum can make the difference and help me out , please contact me , because I feel like I am going to throw another gpu in the can.
