Hi ,
I have an acer aspire 5742g374g32mnkk with damaged ati radeon 5470M graphics card (no display on lcd , vertica lines on external screen when using vga port). 
i was wondering if it's possible to use the Cpui3 370M intel hd graphics card ?
i tried to install it's drivers (intel hd graphics from acer) but i get a message saying that my system doesn't have the minimum requirements.
i also looked at bios settings but found nothing
my lapptop specs : Cpu i3 370M , chipset Mobile intel HM55 Express, Gpu ati radeon 5470M.
