PC random BSOD caused by ATIKMPAG.SYS and boot loops

I have this issue with my computer wherein I get occasional BSODs caused by ATIKMPAG.SYS when I am playing games (League of Legends etc...) or when I am watching movies and stuff. The solution I had with this is to reinstall my video card driver (HD4870) then the problem should be fixed for some time but it will eventually show up again. I also had an issue when it comes to installing the video card drivers. It will tell me that there are warnings during the installation but the logs doesnt show anything. I tried everything to resolve it but it didnt work. What worked for me is to uninstall the device from device manager, restart the computer, then update the video card driver once Windows 7 detected it. This means that I do not have CCC installed but only the drivers.

Another issue I have is that whenever I tried to restart my computer, it will go into boot loop. All I can see is the Gigabyte splash screen then it the computer will lose power. This can also happen when starting my computer for the first time. I was able to get by this problem by switching the PSU off via the switch at the back of the PSU then starting my computer again. The same issue can be experienced when I enter BIOS and quit from it.

With all this stuff happening, is my PSU bad?

My Computer specs:
E8400
Coolermaster V8 CPU cooler
Gigabye EP45 DQ6
Team Elite Xtreme Dark 2GB DDR2 1066
Powercolor HD4870 PCS+
Corsair HX620
Samsung ODD
Western Digital Back 1TB and 640GB
Western Digital Green 2TB


Stuff I already did to fix the problem:
resit the RAM
reposition the RAM
resit the Video card
clean the video card

I cant take my CPU cooler and CPU since I am not that confident when it comes to putting them back together. I had the store to assemble the whole thing when I bought my computer way back 2008.

  1. sounds like the display driver has gone bad, spam f7 and load into safe mode with networking.

    grab a program called driver fusion and the newest drivers for your card.

    uninstall your current amd drivers and dont restart.
    run driver fusion amd driver cleaner then shutdown unplug your power cable and press the pc power button to discharge it.

    plug your power cable back in and boot then reinstall your drivers as display and hdmi driver only.

    I can try that once I got home. Can it be done using the free version of driver fusion?

    yeah, it just wont delete a few of the entries which are system drivers, but will usually clear all the files and registry entries that cause problems
  4. Ok I am gonna try your suggestion tomorrow.
    Queston:
    How do I install the driver and HDMI only? also how different is driver fussion to driver sweeper? That is the tool I used whenever I am going to update my driver. apparently, it stopped working for some reason which gave me the install warnings whenever I tried to install the driver via CCC....
  5. driver fusion is the updated version of driver sweeper, you select custom install to only install display and hdmi driver only.
  6. Ok i just did what you suggested me to do.
    The result was the same. The installer still gave me the installed with warnings and errors but the logs contain no information. Stil no CCC. When I also selected the custom installation option, It showed me 3 components. AMD Catalyst install manager, AMD APP SDK runtime and the HDMI/DP audio driver. Among the three, only the HDMI/DP audio can be unchecked so I just clicked next. The install finished very quickly (less than 10 sec I believe) and gave me the same error when I used driver cleaner. So for me to get the updated driver, once again I updated the display driver via device manager then manually selecting the folder which I extracted the driver installation package from AMD.
  7. any other suggestion guys?
  8. what is the error? are you missing .net framework 3 or 4.5 or something?
  9. There is no error in the logs. its just that the installer is giving me the message that there are warnings/error during the installation.

    I have .net framework installed.
