AMD drivers - I keep having problems installing them... 2×7990 [SOLVED]

I have two 7990s in crossfire and every time I need to update/install AMD drivers, the catalyst installer freezes the PC when it comes to installing gpu drivers.

First I had a problem with the uninstaller as it was saying something I've never seen before and I've seen things... unfortunately didn't write it down. I managed to uninstall ccc using installer (used driver uninstaller from 3d guru and it worked fine) and then installed the latest 14.1 version. It doesn't matter what version I'm installing and what windows (7, 8, 8.1, fresh installs), the installer always freezes when it comes to installing drivers and I always end up resetting the PC.

After few times of doing it, the latest drivers appeared to be installed in device manager (showing the latest version), but ccc installer says otherwise:



I can't easily remove one card as they are watercooled, but this thing is getting on my nerves now...

Anyway, the drivers appears to be installed, only ccc installer thinks otherwise and if I try to install drivers via ccc installer, the PC will crash. It did show 0xB3 BSOD once during drivers installation. Something to do with memory? I have a LCD in my keyboard and when the installation freezes, I can see billions of megabytes used by GPU RAM, this is when I need to press reset button.

Crossfire seems to be working fine too, but I face those crashes EVERY time I get to install new drivers...

No GPU overclock. (only CPU is OCed, but I do not believe it is CPU related)

Any ideas?

Not an expert on water cooling - but while I appreciate it would be difficult to remove one card, how about just removing the PCI-E power cable(s)?

No, that didn't work. Both cards were still recognised.

are you disabling crossfire in CCC and removing the bridge before doing this?

I thought I tried all combinations at that stage...

Unless you are playing BF4 you dont want 14.1 especially as it doesn't support crossfire. Use 13.12 WHQL for now.

Which uninstaller did you use first? If you used AMD uninstaller with W8 then you have ruined your W8 install as it doesnt work with W8. USe either ATIMAN uninstaller for W8 or Display driver uninstaller DDU like you used subsequently.

To check if AMD uninstaller has ruined your OS try doing some admin only tasks such as turning off firewall. Greyed out? If so it has boogered your OS install. I have seen fixes without reinstalling but you'll have to trawl the net and they aren't straight forward.

So firstly - what OS you running?

As for disabling a graphics card, you seem to have a high end motherboard and I've noticed some of them have some switches on the motherboard allowing you to turn off a PCI-e lane. Could you not do this to get it down to 1 card for installing the drivers?

I did what you suggested. I'm running Windows 7 ult. x64 and I used DDU to remove everything. My OS is clean, and this was happening during the very thing installations on fresh systems... anyway, what I did now was I used DDU to remove everything and thanks to GoogalyMoogaly I realised that there are indeed switches for each PCIe slots. I did know it, but never before had to use it :] so I disabled all PCIe's leaving only the first card ON. I also disconnected the bridge and then I installed 13.12 WHQL for the first card. Then I disabled the first card, enabled the second card and then when Windows started Aero was ON, VGA drivers started being installed automatically for the second card at which point, the PC froze and then a blinking cursor appeared on the screen.

I pushed the Reset button.

When Windows started up again, Aero was OFF. In device manager, one of the GPUs had a warning triangle and one GPU was disabled. When I enabled the second GPU, Windows was required to reboot. Windows started up fine with both GPUs installed correctly. I checked with CCC installer as well and it recognised installed drivers.

Then I shut down the PC, connected the bridge, started Windows and all 4 GPUs appeared to be installed correctly. At this point crossfire was Disabled, so I Enabled it and the PC froze again and all I could do was the reset button.

When Windows started up again, crossfire was still disabled so I tried to enable it again and it seems to work fine now. The amount of reboots I did...

Should I stay away from Beta drivers?

I thought I've read somewhere that HD79XX were supported in 14.1 but hey ho...

At least I got it working. I hope. Thanks for your time guys, but I did have issues installing previous versions as well. The pc didn't freeze, but the screen turned black and fortunately I used LogMeIn/TeamViewer to reboot the pc as the power button didn't work... the difference this time was that the PC did freeze during driver installation.
