Random Freezing and Blue Screen
I have a 15'' Macbook Pro with a quad core i7 processor.
For months and months now my computer keeps on freezing, randomly (not related to having any particular program open) to a blank blue screen that does not go away. The only way for me to un-freeze it is close the computer and re-start it or sometimes I have to hold down the power button and shut off the computer. I've taken it to the apple store probably 5 times for this issue and because they are unable to replicate the issue in the store, they don't know what the issue is. I had apple hardware test done, a 24-hour diagnostic, and my operating system completely re-installed done but my computer keeps on freezing blue. Does anyone know why this is?
