Microsoft DirectX Runtime Installer
. Download this and make sure you update your DirectX files. For Windows 7 64-bit it will be about 100MBs of updates. If you get a Cryptograhic Service error or whatever. Download this one here
. It's the June 2010 DirectX redistributable which will contain everything that the first installer installs.
Also if you're going to mess around with drivers get this: Driver Sweeper
. Download this, then reboot computer and go into safe mode, which is commonly done by pressing F8 a few times right after bios. Might take a few times to get it right. Run Driver Sweeper, select ATI Graphics. Let it uninstall all of that. Reboot. Safe mode again and run Driver Sweeper again to make sure all the files are gone.
Then reboot computer normally, no safe mode; then install the latest ATI Catalyst. I am still having problems with the latest Catalyst 10.8 because of my 5770 power save mode. I have to use MSI Afterburner to fix it and make it run right. But this is a BIOS issue. I could easily remedy it with a BIOS mod but eh, just don't feel like messing with it.
