Google Chrome pages go black
There are a number of possible causes for this (e.g. an extension you have installed is running amuck).

However, the first thing I would try on your particular model of MBP is to turn off hardware acceleration in Google Chrome. To do this, follow these steps:


Launch Google Chrome
Go to Chrome > Preferences (or just press the command, keyboard shortcut
At the bottom of the page, click on Show advanced settings...
Look for the System subheading in the new settings that appear
Uncheck the Use hardware acceleration when available option
Restart Google Chrome


Unfortunately, since your issue is intermittent it may not be obvious if this has resolved the problem. But what I can say is that this fixes the problem for many users I've helped (especially on mid-2010 and early-2011 MBP computers).
