Windows 7: ntkrnlmp.exe BSOD random

Windows 7 Ultimate x64
ntkrnlmp.exe BSOD random

I just put together a new computer roughly a month ago and it has been running fine since mid June. Starting on 6/28, I've been getting some random BSODs. I figured out the first two on my own, one was ATI rollover drivers still on my system. I completely cleaned them out on my own, no software, right down to the registry and those stopped. Second, I had to retire AVG. Residence Shield gave me 3 BSODs. Shame too, never had before on my old Q9550. Finally, 2 hours after solving the AVG issue, I was just about to pass out and then I hear my video card fan slow down from 50 to 28 (which is what it does when I restart) I think to myself, you've got to be kidding me. I debug and I got the infamous ntkrnlmp.exe culprit. Looking over the report, the code 0x1a_41201 has me worried it's a memory issue. Here is the report:

Didn't get buried. You are sixth on my priority list behind the other five who had not yet received a response. :)

As to bumping:

You can expect another response from me tonight (~6-7 hours after this post) with my analysis.

If you want a better response, please follow the

Right now, all I can tell you is it is either a memory problem or a driver conflict causing your crashes.

I was kinda hoping you would follow the instructions first. Without them, I cannot be sure whether you have conflicting drivers or software that might indicate a reason for the 0x1A BugCheck code.
