Quite often, an error is displayed on a blue screen Atikmdag sysas a result of incorrect installation of drivers. Its damage is also often to blame. The problem occurs on AMD and ATI Radeon graphics cards. Most often, it is enough to reinstall the drivers or update them to get rid of the problem. However, this does not always help.

Code 0x0000003

This code indicates a completely different problem. Most likely there was a conflict when working with the video driver Win32K. The problem is not difficult to fix. Just download the correct version of the patch. When installing the video driver, be sure to run the program update to automatic mode.

File replacement

When a new version of the program is launched, the old file is sent to System32\drivers. The result is the use of the operating system of the old program. Windows does not use the new one. The result is a blue screen of death (BSOD).

  2. Navigate to the folder address System32\drivers.
  3. Find atikmdag.
  4. Give it an extension .sys.old.
  5. Go to your hard drive C.
  6. Open the folder ATI.
  7. Find sys.
  8. Transfer to your desktop.
  9. Open a command prompt via start.
  10. Enter chdir Desktop, confirm your entry.
  11. Enter the command Expand.exe atikmdag.sy_ atikmdag.sy
  12. Copy the new file on your desktop and send it to your drivers folder.
