Major Slowdown and Bluescreens after Windows Update (6.1.7600.2.0.0.768.3) RRS feed

  • Question

  • I had minor problems prior to doing the latest updates, now they have made my computer almost unusable.

     

    Here are the codes I got from the two bluescreens i had (first one was when i noticed the problem, second was while I was trying to figure out the problem).

    I added the minidump from the second one to my skydrive.

    I have run scans in Spybot, Ad-Aware, as well as Norton IS 2010 with negative results in all of them.

    Any and all help would be appreciated. I am stumped.

  • Have you set up Driver Verifier (Verifier.exe) on your computer? The minidump shows a special Driver Verifier bugcheck (0xc4) pointing to a MagicDisc driver (Mcdbus.sys) as the possible culprit. Uninstall that application temporarily and see if the system becomes stable.

    It is important to note that if you're NOT testing your drivers you should disable Driver Verifier because it slows down your computer. To disable Driver Verifier follow these steps:

    Click Start, type verifier.exe, press ENTER, choose Delete existing settings, and then click Finish. Reboot your computer.

  • Please check if the blue screen issue can be resolved by performing a System Restore. For the detailed steps, please refer to this article: What are the system recovery options in Windows 7?

     

    If the blue screen issue can be resolved after the restore, remove MagicIso and MagicDisc to see if the issue can be resolved.

  • Open device manager an rollback the graphic driver.

    Set windows update not to install optional updates automatically.

    Find your graphic card's website, download and install the specific driver for your card model.
