HELP! 7990 wont install drivers

[daimyo]

Hi guys,

I got 2 7990s on a Asrock z77 extreme MB. Installed win 7 64x and cant install the drivers for the video... says "No AMD drivers were installed or the AMD driver is not functioning"

What can I do?

Have you tried a earlier driver release or have you just gone for the new 13.11 drivers??

First installed the 13.1 catalyst, then the driver that came with the cd... same thang

Have you removed any old drivers that could still be on the system?

Are the gpus both hooked up to power cables? Or seated into the slots correctly? Check all connections first. If not that then software problem.

How many monitors are connected?
Are they using display ports? Have you tried disconnecting all but the main monitor? (I'm sure I've read somewhere that that helps sometimes)
