kompulsive,
Your posts does come off as peculiar to me. However, I've been keeping tabs on this thread and it appears that you may have some sort of registry issue. There was no response to my previous post when I asked you to set the monitor to 59Hz. Regardless, after looking at your most recent pic it appears that you are either:
A. Using dual monitors (if so disable the 2ndary monitor)
B. Have duplicate driver entries in the registry
(IE: why I say the registry maybe the problem).
Here is what you should do. Uninstall the drivers you are currently using
Reboot
Open the Command Prompt Window (using the Run As Administrator option) & enter the command: SET DEVMGR_SHOW_NONPRESENT_DEVICES=1.
Afterwards type devmgmt.msc (this will take you to the Device Manager)
Choose View, Show Hidden Devices
The new instance of Device Manager will now show “ghosted” entries for devices that were once present. Go to your Monitors and Display Adapters and see if there are any duplicate ghost (grayed out) entries for your Monitor and your Video Card (4870 X2). Delete those duplicate entries. Do not delete the entry that is visible or in this case appear to be bold typed.
Next go to Sound, Video and Game Controllers and look for ghosted, duplicate entries for ATI Function Driver for High Definition Audio... Delete them (making sure you don't delete the one that appears to be in bold text.
Once completed Reboot
Go to Start, Run and type Regedit (with adminstrator rights). Go to Edit, Find and type in "DefaultSettings.VRefresh" (without the quotes). Which is found in HKEY_CURRENT_CONFIG\System\CurrentControlSet\CONTROL\VIDEO. See if it reads 59 or 60. If it's 59 change it to 60 by right clicking on the dword (which is DefaultSettings.VRefresh) and changing the Hexidecimal from 3b to 3c (yes a lower case c). Or you can click on "decimal" and change the number from 59 to 60. Either way should work. After you make the change make sure it now reads 60.
Next hit the F3 key and look for other entries that may read 59. If so, change those as well.
Once completed exit the registry (make sure you made no mistakes). Double check your work.
Next Reboot your PC
Once the PC is rebooted now use Driver Cleaner (or whatever program you are using) and clean out all Radeon related drivers, files, etc
Reboot again
Make sure you have either .netframe work 2.0 + .netframe works 2.0 SP1 or .netframe work 3.5. Don't have both installed.
Make sure
Microsoft Visual C++ 2008 Redistributable Package (x86) or
Microsoft Visual C++ 2008 Feature Pack Redistributable Package (x64) installed on your PC. I believe that Visual C++ 2005 is installed when the cat is installed. However, check to see what you have.
Once rebooted, install Cat 9.1. Follow all instructions.
You may or may not be asked to reboot your PC. In any case once reboot your PC one more time. See if there is any improvement.
