I've rigoursly searched for post that specificllay details my situatuion. Couldn't find one. So I'm posting it here:
My computer - SOMETIMES - displays little discolored squares in the startup menu and in the space above a open window or application. When I scroll my mouse, they flicker and change place somewhere on the startup or window. And, when I open CCC, the infamous pink bars of card faliure/bad driver installation appear. I've reinstalled the drivers - currently running on the 12.1, and the problem came back when I brought my computer back from sleep while I was out.
I decided to open my case up, take the card out, and put it back in...
When I turned the computer on, the bars in the startup menu were gone. However, CCC still had pink slits when opened. My computer said it was installing some updates and when it finished it asked to restart the comp. So I did that.
Now CCC is fine. And so is the startup.
At no point, before or after the problem, have any of my games displayed the pink bars or like discoloured squares...
The problem seems to come and go.
Could it be only when my computer goes to sleep?
It's really quite odd.
Are my cards dying?
This is my setup:
8 GB RAM
i5 2500k (o'ced to 4.5 ghz with corsair water cooling)
Haven't physically tried. But I disabled crossfirex through CCC and it didn't remove the problem. It's not much of an issue; it doesn't interfere with game play. I'm just worried that its an early symptom of something more serious.
Removing the second GPU, physically, is intended to rule out a heat or power issue (the usual culprits for these sorts of issues). Even if disabled in Windows, the device will still draw some power and restrict airflow.
Batman Arkham City. It run's terrible. Even on medium settings, the dips are unbearable. It goes from 60-50-40-50-40-50-60. Also, Assassin's Creed II runs pretty bad. Skyrim runs alright. Actually, it runs great - 60 fps all the time, occasional dips to 50 in certain areas like Markarth and Riften (due to fog and water effects probably). But I have to run Skyrim in windowed mode, and disable my other card, because indoors it reads 60 fps - but the stuttering is unbelievable. Its like watching a stop motion picture. So I run the game in windowed mode. And while it runs fine, I feel a bit cheated (considering I have another 360 dollar card laying dormant beside the one I'm using).
I don't know. The drive support is pretty damn bad.
