    BSOD when booting, atikmpag.sys error


    Hi can anyone please help me, I installed fresh windows on an new Hdd and installed my graphic card driver and restarted then after windows logo shows I get BSOD.. only way to use it now is in safemode

    Acer Aspire 5552G

    Specs
    OS: Windows 7 Gamer (Based on Windows 7 ultimate)
    Motherboard: JE51_DN
    CPU: AMD Phenom II N850 Triple-Core Processor
    GPU: AMD Mobility Radeon HD 5000 Series

    What I've tried to Fix it that didn't work:
    - uninstalled AMD/ATI files and traces including registry and tried updating/reinstalling newest versions
    - reseated CPU, RAM
    - ran memory tests and passed
    - tried using 14.9 / 14.12 amd catalyst drivers
    - tried the windows expand method for atikmdag.sys / atikmpag.sys
    - memtest
    - all files on HDD seem to work, and are non-corrupted

    the problem lies in the last update to your graphics driver, rollback the driver and see if the issue persists, this may have happened because the driver file was corrupted when updating it.

    Hello, CrayCeets. All of your dump files are from today. Please go to Acer's web site and download their most current Graphics driver. Uninstall the current driver and clean up the left over drivers using this tutorial Drivers - Clean Left over Files after Uninstalling. Select only ATI Display drivers Then after the reboot install the driver from Acer. Most OEMs alter their drivers to work with their laptops the way they designed them. Drivers downloaded from anywhere else will usually not work right, or work at all.
