Hi, these aren't Catalyst (video graphics) drivers. They're chipset drivers that usually offer extended support for your system like AHCI and USB. It should clear up some problems you may be having. There are other questions, like when did this problem start, have you installed anything new recently?
If not, you may want to do a system restore and see if you still get the error you have now. Phenom II is relatively old, but if those chipset drivers are incompatible, the installer will let you know. There should be no question to install Catalyst drivers at all - that is not what these are for.
Because your processor is an older model, I will be a bit surprised if this works for you. Make sure you click on the Windows 7 tab on that...
