I did read about your graphics issue. There are a number of causes for this. It could be something as simple as having the monitor too close to a stereo speaker. The magnet inside the speaker can cause the screen act in this manner. Other electronic devices can as well. Have you recently moved the monitor or set something close to it? Even if such is not the case try moving the monitor around a little if possible to a new location just to see if the rippling effects change at all. I would like to see a screenshot of what you are referring to if possible.
I think I was mainly getting the bsod when using FFox,
According to your previous post you were using FireFox during at least one of your bsod's. However, the dump file shows the crash was actually caused by COMODO Internet Security Helper Driver.
Aside from the graphics issue, which I will continue to research, there is nothing we can do other than wait to see if the crashes stop as a result of the task you performed yesterday.
