Blue Screen Windows 7 Third Time

My wife's windows 7 desktop encountered a blue screen error today for the third time. See attached.
Can you assist?📎BSOD 1.21.15.txt

Look in c:\windows\minidump, see if there are any .dmp files there. If yes, zip them up and upload here so we can look at them.

 

To upload, click on More reply options, then use the Browse and Attach this file button below the message input area.

There are 5 files. I could only attach one. They appear to be duplicates. See what you can do. Thanks  

Dump indicates dxgmms1.sys as the problem. Try updating your video driver.

 

What is the make and full model number of the computer?

What does Device Manager show for your Display Adapter (make and model)?

I will get back to you as soon as I can.
