So, I just bought an ASUS R9 280. When I tried to install it it gave me a black screen and I couldn't even see the BIOS. My motherboard (P67H2-A3) doesn't have integrated graphics.
But it works with other video cards (tried 6670, and a GTX 750).
When you put the card in it doesn't do anything, just black screen, after putting another it says the CMOS is corrupt and I need to reset defaults on the BIOS configuration.
I know it's not the card because I put it in another computer and I could use it just fine. (Although just in safe mode, but I assume that's a different driver problem).
My last resource is to flash a new BIOS version (I have 7.x.x.x.x on the ME version). But I want to try and ask for help first.
Also this is my first post. If I did something wrong please let me know.
