I got a 2nd hand ASUS G71V. Can I upgrade it to Win 10? Well, I already tried. I installed Win 10 Pro 64 bit without hickup but I have a lot of yellow exclaimation marks in Hardware Manager. It is quite obvious that I need the motherboard driver and card reader driver, etc. But on ASUS website there are only drivers for Win 7 to download. I couldn't get the Win 8 driver as it requires log in. Any suggestion is most appreciated. Many thanks in advance.
