Random BSOD Please help

[8986103t]

Hello,

Normally BSOD happened when I am playing League of Legends, or using lightroom.
I was using 32bit window7 with 4gb RAM, at first, i thought it was because lack of physical memory,
so i installed 3 more 4gb RAM, now it becomes 16gb RAM and I installed a new 64 bit window7.
It seems it got better after that, but BSOD still happened sometimes. I dont know why.

One more thing is when i play League of Legends, the graph is not stable, some horizontal lines will show on the screen, kind of flickering

There is only one crash dump in the zip; and that one is caused by DisplayLink.
