lenovo g50-45 bios update

bought this recently, and must say that i am pretty pissed. i did installation of windows 7 on it and it worked fine for some 10 days till it got BSOD cause of bad system info and couldnt even load into windows. only solution was to reinstall. i did fresh install and i got BSOD with fresh install after only few days.


checked internet for solution and saw that you could select windows 7 os in bios for optimized settings that should prevent BSOD. but no option for windows 7 in bios. only for win 8 and other OS.


i thought ok, i will just download latest bios and flash it. but what happened when i downloaded bios (a2cn38ww) from support page?

i got this message "your machine does not match with this bios".


so does anyone know where i can actually  download correct bios, or how to contact lenovo support so they can tell me where to download bios?
