Black Screen After Windows Logo (ATI HD 6990M)

Graphics Card:

Radeon HD 6990M

No Overclocking



AMD Catalyst Driver Version, and Driver History:

Latest ATI drivers as well as drivers provided from the Sager website.



Operating System:

Windows 7 Ultimate 64 bit SP1



Issue Details:

The problem started while I was watching a video with VLC media player. I quickly paused then unpaused the video and suddenly the whole screen went black. After the screen went black there was no further hard drive activity.

Alt-tabbing and ctrl-alt-del'ing had no effect.

I restarted the computer and after the bios and windows logo screens the screen went black again.

I restarted in safe mode and uninstalled all amd drivers using Driver Sweeper 2.1.0, uninstalled CCC and uninstalled the device from the device manager. Then restarted. The screen works until I reinstall CCC with drivers (both Sager's drivers and the latest from AMD). I restart and the screen goes black again after the Windows logo. I also tried doing all the above plus manually deleting all ati drivers in the windows/system32/drivers folder.

Also, sometimes when starting the computer (instead of getting the black screen) I get a BSOD with an error in atikmpag.sys

  1. I have the exact same setup as you. And am running into the exact same problem besides getting the BSOD. Found anything out yet?
  2. Try the 12.10 drivers, they seem to be the most stable at the moment.
