Problems with HD 6990

After a few months finally got Asus Rampage IV Gene as a replacement for my dead Asus Rampage IV Formula but seems like I can't get my Asus HD 6990 to work properly.

Only one GPU shows up in Device Manager no matter what I do. Tried to uninstall drivers completely using DDU and then install different versions with mixed results - sometimes installation package freezes on AMD Display Driver but most of the times it's fine but the problem is that afterwards I always get "No AMD graphics is installed" message.

Does it have something to do with famous crossfire bug on old dual cards or it's just my half-dead 6990?

Full specs:

Asus Formula IV Rampage

Core I7 3820

Asus HD 6990

Nvidia GT 610

Asus Xonar DX

Kingston HyperX 12GB Ram+Noname 4GB Ram

3*1TB HDD (WD and Seagate)

Old Philips 170C Monitor (connected to HD 6990 via VGA-DVI connector)

OS - Windows 10 Pro 64 bit

AMD Drivers - tried 15.7 and 15.71 with no results then cleaned everything with Driver Fusion and DDU and installed 16.1.1 Crimson Beta as it's the latest and the last release for my card as far as I know
