Hello, I am having a small BSOD issue. I got my first error last night - stating some issue with my RTKHDA driver - to which, I downloaded and installed the update. (R2.66) No issues. Figured, I'd update my video card drivers while I was at it (285.58)- no issues. Then today, I go to quit playing Left 4 Dead, (I had played Arkham city, Left 4 Dead 2 and Dead Island yesterday and today - no issues whatsoever) - and as soon as I hit quit - Bam! BSOD : Win32k.sys - System Service Exception Hoping to get some help in a couple of areas: 1. Figuring out the cause of the BSOD errors 2. Advice on how to identify, and update my drivers as easily as possible 3. Finally, fixing the errors. I am attaching a copy of each of the mini dump files (2), as well as an updated copy of my dxdiag (txt and xml versions) in order to help facilitate my requests. Any help would be appreciated.
