Go run memory test, if there are no other evident problems. If stuff happens *randomly*, it's most likely the effect of a bad memory element(s) and ASLR that makes the hole(s) affect different processes in the OS.

The errors are not random, although they happen randomly. It's always "uncorrectable error" BSOD. My most likely candidate at this point is the video card. First crashes started when I was using that heavily (rendering images AND watching youtube in fullscreen). Now it happens even when I'm not using it heavily, like during web browsing when Chrome is the only thing running. Even with old drivers that I know used to work back in spring. Will do memory check as well. Next step is to go with the onboard video.
