Monitor flashes black screen randomly with Raedon HD4670 video card

[badbigdad]

I recently changed the Catalyst Control Center settings (can't remember exact changes) and now my screen goes black for 2-3 seconds at a time randomly. I removed the display driver and Catalyst Control Center and let Windows Update install a new version on a reboot. I've had the card for many years with no problem like this before.

How can I erase the entire video driver/software configuration and re-install it to get back to normal?

Thanks in advance,

Assuming you have the current Catalyst driver downloaded for your "legacy" HD4670 and ready for use in a reinstall, one clean way to remove all existing AMD software and drivers guaranteed is to use "Driver Fusion" from Treexy (this used to be called "Driver Sweeper").

It comes in a free version, and there also is a non-free premium version. The free version is sufficient to remove everything for the supported audio and video vendors, including of course AMD, nVidia and Intel on the video side.

You click on "Maintenance", and then "Driver Family", then "Display", then "AMD". Follow the "delete" process from there, and when it completes you reboot. You've now completely removed every trace of AMD, including from the Registry.

You can now reinstall your Catalyst driver from scratch.
