T440 0x0000004a Blue Screen error

2014-10-23, 16:20 PM

0x0000004a Blue Screen error.  This happens at different times: log in, working in various office programs, before it gets to the log in screen.

 

System update has updated the laptop fully and it has all windows updates.  It is a stock build of Win7 Pro (shipped with this OS).

 

Here are recent dump files, any help is greatly appreciated.

Hi Derekge,

 

Welcome to Lenovo Community!

 

As per the query we understood that you facing issue with BSOD on your ThinkPad T440.

 

To resolve the issue please follow the steps from below link, is the issue doesn’t resolve then I suggest you to provide us the Minidump file from C:\Windows\Minidump folder, so that we will verify the file and assist you further on that.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Do you have Bitdefender installed?  That will do it. 

 

If not, download and run Memtest.  Let it run for at least 12 hours.  If it throws errors, replace the RAM.
