I Installed a driver update for my display driver and ever since then I get this message on startup: "No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for your AMD hardware."

I have a Radeon HD 7770 so I'm unsure why i'm getting this message, any help is appriciated.

 AMD Radeon HD7770 2GB
 No Over clocking.

AMD Catalyst Driver Version, and Driver History
Unknown. Tried most recent update. Was using the version that came shipped with my computer.

Windows 7 64 bit

Issue Details
Get the message about it not finding my graphics card, also have an issue where sometimes I get the message about it saying my display driver has stopped working and that it has recovered. I think this is causing an issue with DCS: A-10C and it constantly freezing.

Installed .NET Framework 4.5 and restared my computer. Still getting the same error message about it not finding my card.

You have to install the drivers after you install the netframeworks. Follow this > http://forums.amd.com/game/messageview.cfm?catid=444&threadid=162444&enterthread=y

My bad, going with a fresh install to be safe, deleted the install manager and I'm on the part with Driver Sweeper. You say to delete "AMD Graphics", I don't have that but I have "AMD Display" is that safe to delete?

Yes.....same thing.

Still no luck, during the install I got an error about it needing a digitally signed driver about two items, I didn't get to read them fully.

EDit: Went to device manager to look at my card, I noticed there is a yellow triangle on it with an exclamation point, Clicked on it and got:

"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

Edit of the Edit: Updated driver from there to fix the card and reran th catalyst installer. CCC just won't open (no error, just not open) and neither will my steam games.
