Method 10: Replacing the old version of atikmdag.sys with an updated copy.

Make sure you have your ATi drivers updated. If you are unsure of what you are doing, make sure to have someone who has experience in modifying system files. Navigate to your C:Windows\System32\drivers (assuming Windows is installed in C: with default path). Look for atikmdag.sys and hover your mouse over it. If this driver version number is different from the latest driver version, it needs to replaced. So what you do is:

1. Download the latest driver version and extract the contents of the .exe file (this should happen when you double click on the .exe, if not, use 7zip to extract it).
2. Rename your current atikmdag.sys file to atikmdag.sys.old.
3. Look for atikmdag.sy_ in the folder where you extracted the latest drivers.
4. Copy atikmdag.sy_ to WindowsSystem32drivers folder.
5. Open command prompt in Administrator mode (start menu->programs->accessories->right click command prompt->Run as Administrator).
6. Navigate to your Windows\System32\drivers folder. (example cd C:\Windows\System32\drivers)
7. Type expand atikmdag.sy_ atikmdag.sys
8. Reboot computer.

For most people, this has solved the problem completely. If the problem still exists, don’t worry, this method didn’t work for me either.

    Did not work for me.
    Gonna try the other ones

    PS : prb is not specific to one graphics card (ATI HD 4350 for me). On the same computer (Dell Inspiron) I have the same prb with the standard Intel graphics card (igfx driver not responding)

    Means it is more a chipset problem ?

    this solution fix these error for me:
    Event ID 43029 that says “Display in not active”, Event ID 52236 that says “CPLIB :: General – Invalid Parameter”

    Before applying this solution, I got these errors every time I start my windows 7 or vista (the errors are listed in Event Viewer, System).
    But it still crash everytime I play a game :(

    could be the PSU not giving enough power. how many watts is it?

    I fixed the problem by uninstalling the old drivers and ATI Catalyst Control Center and then installed the latest drivers with latest Catalyst.

    I was having problem with Mass Effect in Vista. It used to crash to black screen.

    Hope this helps someone :)

    BTW. I’m on ATI Radeon HD 4870 X2

    I received Event ID 52236 and random BSODs for three months before I solved my problem (see http://social.technet.microsoft.com/Forums/en-US/w7itproperf/thread/78e2e971-7fe9-41fc-8f7c-238264bd8b30).

    Basically I found out that when I upgraded my driver, I installed the wrong one. Though I tried reinstalling it several times, I always used the wrong one.

    Instead of getting the driver for an ATI Mobility Radeon HD 4200, I got the one for ATI Radeon HD 4200. I don’t know why they use the same model numbers for desktop and notebook versions. When I finally realized the problem by using ATI’s auto detect tool, it saved me the price of a new computer.

    It sounds ridiculously simple, but I can’t be the only one who made this mistake.
