im currently using an Gigabyte H77N-Wifi motherboard and i noticed that the ram for IGP was locked on 64mb, i tried putting it up higher since i have an 8 gig ram to spare... but it wont run POST... what should i do? did i forgot something? does having it connected to the HDMI port affects it?
did u check it in Internal Graphics Memory Size? Is should be available from 32M to 1024M and manual settings there.
Check your bios settings and with basic procedure to clear cmos and return to default, and try it again.
If still failure there, update your bios and try it again.
