To see if your problem is to do with the graphics card (and as I suspect the memory of the on-board graphics) can you temporarily get a dedicated graphics card and try that to see if the problem goes?
This help you determine where to focus your efforts (and money).
I'm still betting that dual channel mode for memory will solve your issues, but this is a good way to test.
