I'm running Windows 7 Premium Home-64 Bit, and have 2 Radeon HD 7770's in crossfire. the computer came with Catalyst Control Center (CCC) 12.1. The first day i got it i tried to go to 12.2. During the middle of the install, the screen always went black with the blinking cursor in the top left corner and stayed there. I have let it sit for hours before and nothing would happen, i can't type anything and i can't even turn the numlock off on the keyboard. So i would have to force shutdown then boot in safe mode and go through the process multiple times until CCC was uninstalled and the computer wouldn't blank to that screen again when i start up. So i figured it was just a 12.2 issue and went back to 12.1 (which i was only able to install from the CD).
12.3 comes out a few days ago and after multiple attempts the same thing is happening.
So i uninstalled Catalyst and when i booted to install 12.1 i noticed the computer recognized the cards and said their drivers were up to date. So i played a few games. with CCC 12.1 World of Warcraft would max at at 140 FPS, never anymore. Now with No CCC installed WoW is playing at 200-250 FPS. If i only played WoW i wouldn't even bother trying to fix this problem. The issue is that i have seen some graphics issues in other games i play, and im hoping the newer drivers will fix it. In Star Wars: the Old Republic sometimes text and buttons in the UI flash very quickly and also sometimes rainbow stripes flash in the screen, they change shape and move around if there is movement or the camera moves. Also in Starcraft 2 sometimes there are square blocks in the terrain that flash and are off colored. The computer is brand new and has a good motherboard, i7 processor and 16 gigs of ram, I'm quite certain i meet all minimum requirements for all these games.
While CCC 12.1 was installed I clocked both cards up to 1.1 ghz (up from 1 ghz), and i also went into the registry and turned off ULPS, as it was something that was highly recommended in a few threads that i read. I don't think this has anything to do with it.
I really don't even know where to start to fix this problem. Any thoughts?
