Mobo cannot detect graphics card

[mixadenz]

Yesterday I built my first computer. Everything was fine until I noticed, that my graphics card fans are not spinning and my system and mobo don't see the card. It turns on for two seconds, starts spinning and working and then that's it. The display works and I'm connected to the card, but the system shows igu, which is very strange.
I've tried the card on another computer, fans are spinning, but no display.

I did. I have Windows 8.1 and I couldn't find drivers on asus website. I have a cd though. I also tried w7 drivers, didn't work either.

They don't have w8.1 version there.

Will do as soon as I get home, thanks.
The device manager show 256mb card only, even though hdmi is connected to rx570, btw.

I sent a link with the 8.1 driver above.
