Every time my windows 7 boots there is somewhat of a heavy distortion in the screen. ie when the screen "Windows is starting" appears there is a distortion.
It started with a 7 update. One particular update took more than 2 hours to install when I shut my machine down. Understandable I was annoyed and removed the battery to force it to power off (its my lap top btw). After that every time I boot I find this distortion.
But from there on windows works normally.
