I get screen scrambling in Windows 7 almost everyday. I don't know what causes it, but I'm guessing something must have tripped the DRM system. It occurs randomly, but can happen as fast as a few minutes after a boot, to several hours of usage. What my screen looks like during scrambling is if you've ever had an old CRT monitor, it looks like it's trying to show an unsupported screen resolution. The interesting part is that it's somehow correlated with the mouse pointer. If I move the mouse pointer to the bottom of the screen, I can sometimes get the scrambling to stop. Soon as I move it up, the scrambling restarts. Also, scrambling is worst on the part of the screen right below the mouse pointer. I've encountered this before at around Vista launch. I've always thought that it was a driver related issue. But, by the time Win 7 was released two years later, this should have been resolved, but didn't, which led me to think DRM system being tripped as Vista was the beginning of implementation of such DRM system. I'm usually doing things like surfing the web when this happens. Not even trying to play video illegally, etc. Anyways, if anyone else has a similar symptom of scrambling screen on their PC laptop, how did you manage to permanently fix it?
