Graphics Card: Sapphire Radeon R7 260X
Motherboard: Asus M4N68T-M V2
OS: Windows 7 64bit
I installed a new graphics card and after much fighting with it (updated the bios, uninstalled and installed drivers a million times) I finally got it to work! Then, I shut down the computer. Now when I turn it back on I get an error from Catalyst saying "No amd graphics driver installed or is not functioning properly. Please install the amd driver appropiate for your amd software". The drivers are installed but when I open the Catalyst Control Center I'm missing a bunch of the options that were there when the card worked properly. The card is still showing up in the device manager (which is a step up from the problems I'd been having) and when I have windows search for updates to the card driver it says the drivers are up to date. I've of course uninstalled and installed the drivers again but my monitor still doesn't detect anything from the graphics card.
Another post suggested that I disable the digital driver signature which I've done follow these steps I found on a Windows help forum but it didn't have any effect:
Any additional suggestions?
Thanks in advance!

go to "All Programs", then "Accessories", right-click on "Command Prompt" and choose "Run as administrator".
1. Now type the following and press <Enter> after each line:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
2. Restart your computer
3. This will disable your Windows 7 driver signing.
If this did NOT work for you, here is another way to disable Windows 7 driver signing.
1. restart your computer, continuously press <F8> to get to Advanced Boot Options. Note: On some systems, you need to first press <F2> to go into Boot Menu, then press <F8> to reach Advanced Boot Options.
2. When the menu appears, use the DOWN arrow key to scroll to “Disable Driver Signature Enforcement.”
3. Press <Enter>.
4. Continue the boot process.
after booting an amd command prompt windows will appear, and it will disappear after few second.
it means your amd driver has been installed. now you can open the catalyst control centre.
or you can reinstall the driver, this time this error will no come.
Any additional suggestions?
Thanks in advance!
