In addition, the Windows aero surface flickers in a few second's interval.
I've deinstalled the driver and went back to the Catalyst_12.11_Beta11, but the problems persist (although not as bad as before).
GPU temp is okay.
Sign in as administrator (If you are not administrator you may be blocked)
Close all the applications that are being used...save and close your files...
Turn Off the antivirus and firewall, turn off the functions of windows defender.
If you have multiple security programs installed, they must be turned ALL off. Security will prevent your driver from installing...
Download the latest CCC driver package, and save it to an easy location. Make sure this is the correct driver for your card.
Delete all the current AMD video software and drivers, restart the system (the video will look screwy, don't worry)
Now load install all the newest CCC drivers and restart the system (the driver will not work (yet) as you said, but load it anyway)
left click start
left click computer
right click C drive
Left click Open
Right click Users
Left click properties
"Check" mark the box that says: Attributes: "Hidden" (there is now a check-mark in the "Hidden" box)
Now the system will apply the hidden attributes...and this will take a while, or maybe a long while. Let this proceed, and don't interrupt it...
During this procedure, a message may inform you that you do not have administrator privilege to the file you are trying to change the attributes of. That's OK. Just click: "ignore all."
When this procedure is finished, click OK (the box will close after you click OK)
Now you will once again be looking at folders in C drive (don’t close the C drive window or you may regret it)
(once again) right click Users
(once again) left click properties
UN- check the box that says: Attributes "Hidden" (you will now take the check mark OUT, Hidden is no longer checked)
Now the computer will UN-apply the hidden attributes, and it may take a while, or a long while...but let it proceed, and finish, don't interrupt it.
During this procedure, a message may inform you that you are not the administrator of the file that you are trying to change the attributes of. That's OK, just click: "ignore all."
When this is completed click OK
Now close all windows and restart the computer
turn all the security back on.
At this point, the CCC should be functional. Open the ccc and test drive.
While deinstalling all Catalyst software, Windows decided to reinstall the graphics driver. So I deinstalled it again, then rebooted. Right after reboot Windows installed the graphics driver again (before I got to install the latest CCC).
I then installed the CCC after all and continued as you wrote.
I'm going to see if it helped (although I doubt it).
