Blue Screen issue Error " BCCode: 4a"

Question

Original Title: Blue Screen issue

Was wondering why my computer keeps crashing to blue screen.  This is highly unusual on my system that I have owned for at least 4 years.  Am fairly savy with computers.  Is this a result of a windows update?  I am really hoping not to have to reinstall windows as I have WAY to much on this computer

Seems it is always relating to ntoskrnl.exe

Answer 2

I have also reset in EFI bios my i5 2500k to 3.30Ghz which I believe is stock performance.  I may have overclocked earlier somewhat by accident.... think it was set to try to achieve 4.20Ghz

Hope this link gets you to the .rar file containing dump files

Hi,

In order to assist you, we will need the DMP files to analyze what exactly occurred at the time of the crash, etc.

If you don't know where DMP files are located, here's how to get to them:

 1.    Navigate to the %systemroot%\Minidump folder.

 2.    Copy any and all DMP files in the Minidump folder to your Desktop and then zip up these files.

 3.    Upload the zip containing the DMP files to Skydrive or a hosting site of your choice and paste in your reply.

If you are going to use Skydrive but don't know how to upload to it, please visit the following:

http://www.wikihow.com/Use-SkyDrive

Please note that any "cleaner" programs such as TuneUp Utilities, CCleaner, etc, by default will delete DMP files upon use.

If your computer is not generating DMP files, please do the following:

1. Start > type %systemroot% which should show the Windows folder, click on it. Once inside that folder, ensure there is a Minidump folder created. If not, CTRL-SHIFT-N to make a New Folder and name it Minidump.
2. Windows key + Pause key. This should bring up System. Click Advanced System Settings on the left > Advanced > Performance > Settings > Advanced > Ensure there's a check-mark for 'Automatically manage paging file size for all drives'.
3. Windows key + Pause key. This should bring up System. Click Advanced System Settings on the left > Advanced > Startup and Recovery > Settings > System Failure > ensure there is a check mark next to 'Write an event to the system log'.

Ensure Small Memory Dump is selected and ensure the path is %systemroot%\Minidump.

4. Double check that the WERS is ENABLED:

Start > Search > type services.msc > Under the name tab, find Windows Error Reporting Service > If the status of the service is not Started then right click it and select Start. Also ensure that under Startup Type it is set to Automatic rather than Manual. You can do this by right clicking it, selecting properties, and under General selecting startup type to 'Automatic', and then click Apply.

If you cannot get into normal mode to do any of this, please do this via Safe Mode.

Regards,

Patrick

Answer 5

We do need the actual DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

We prefer at least 2 DMP files to spot trends and confirm the cause.
