my mother board went bad on me so i had to buy a new one i ended up getting a ASRock Z77 Extreme4 everything went fine except when i went to use my graphics card (Powercolor HD 7870 Vortex II) i couldn't get it to work. i read that sometimes you need to reinstall it when you change a motherboard out so thats what i did but i still cant get it to work. i used the removal tool from AMD to uninstall everything and then downloaded the proper driver for my card but when i hooked it up it still wont work. i made sure the bios on the new motherboard was also set to use the PCI slot as the main graphics. As far as i can tell it should work but i get nothing. im trying to hook it up using HDMI i dont know if that makes any difference or not but i dont have a DVI to test that with. any suggestions would be helpful.
Is windows fully updated ?.
Does it boot up, access to mobo bios, power to card ?.
Is mobo bios set to run card in legacy mode (card will not work in UEFI) ?.
What OS ?.
