Asus P8B75-M / Sapphire R9 270 Vapor-x no iGPU in motherboard BIOS !?

[plm82]

How could i install this video card when the motherboard doesn't seems to have any onboard display(no card plugged in pcie and DVI plugged into motherboard, i still hear the 3 ''beeps'').
No ''iGPU'' option in BIOS and BIOS is updated.
Currently using Radeon HD7300 in pcie slot but when i put the new one, i also get the 3 ''beeps''.
Removing current card, with battery for a minute and trying only HDMI motherboard plug would resolve this, to at least get the ''iGPU'' working so i can boot with the new card installed?

Try removing all your rams and just run it even though if it does not give visual. See if it give beeps. Try this with all your hardware one by one remove one and connect the other one. See what hardware do you remove from which the beeps stop coming.
