Thanks Golden for the reply.
I did, as per your instructions:
- installed MSE, and removed AVG
- updated ATI drivers, but
- was unable to see/check if the dxgkrnl.sys was updated through win update.

During win update I had the next BSOD reporting problem with amdxata.sys (0x000000FC).


Waiting for your reply, as my knowledge to fix this problem has already been exhausted.

I'll have a look at this when I get home this evening.
